Experimental study on soil improvement by electrochemical injection coupled with anode movement technique

An improved electroosmotic method which involves coupling anode movement with injection of calcium chloride (CaCl2) solution into soils during the electroosmotic process was proposed in this paper. The laboratory-based experimental study was conducted in a custom-designed test set-up to assess the effectiveness of the proposed method. During the electroosmotic process, the drained water, drainage rate, electric current, electric resistance, power consumption, settlement, and penetration resistance were monitored. The experimental study showed that after treatment, the drainage volume was about 3.5 times that of the pure electroosmotic, 1.6 times that of the electroosmotic process with injection only, and 2.4 times that of the electroosmotic process with anode movement only. Further, electrochemical injection coupled with anode movement can significantly reduce the non-uniform electrochemical changes in the treated samples, resulting in a relatively uniform settlement and considerable cementation area throughout the sample. The results demonstrate that using this method can effectively alleviate anode corrosion, double the voltage gradient and mitigate the electric resistance increase, further enhancing electroosmotic treatment efficiency.

Experimental and numerical evaluation of sustainable application of steel slag as an alternative to gravel in compaction piles

The study investigates the application of steel slag as an innovative material for compaction piles in the stabilization of soft soils, offering an eco-friendly alternative to conventional gravel compaction piles (GCPs). Through a comprehensive series of laboratory tests, field experiments, and numerical simulations, this study evaluated the performance, environmental impact, and long-term behavior of steel slag compaction piles (SSCPs). The key findings revealed that steel slag not only provides immediate soil improvement comparable to gravel but also exhibits significant time-dependent increases in strength and stiffness. Standard Penetration Test (SPT) N-ratios (N1/N0, where N1 = N value after improvement and N0 = N value before improvement) were similar for soils reinforced with SSCPs and GCPs after 0 months, but were about 30 % higher in SSCP-reinforced soils after 3 months. This increase was attributed to the cementation of steel slags, suggesting that the compaction pile with increased stiffness due to cementation acts as a compaction pile with an increased area replacement ratio (α). Environmental assessments confirmed that steel slag meets regulatory standards for soil contamination, positioning it as a sustainable option. Settlement analysis after embankment construction showed reduced and more uniform settlements with SSCPs, suggesting superior load distribution capabilities. Finite element analysis compared the behavior of SSCP-reinforced soils at varying α and stiffness of compaction piles, confirming that the cementation of steel slag produces an effect equivalent to increasing α in uncemented piles, thus enhancing the reinforcement effect.

Foreign migrants in the Moscow agglomeration: spatial and temporal analysis based on data from mobile operators

The article analyzes the modern ethnic landscape of the Moscow agglomeration on the basis of data from mobile operators. The estimation of the number of foreign migrants and its monthly dynamics from October 2021 to October 2022 is made. The main areas of residence of foreigners have been identified, the ethnic diversity of municipalities has been assessed, and the main types of settlement pattern of national-ethnic communities have been identified. The study showed that the total number of foreign migrants in the agglomeration reaches 1.8 million people or 9% of the total population, remaining almost unchanged in spite of events of 2022, including the special military operation. The share of foreigners is minimal in ZATO (below 3%), it is also insignificant in the far suburbs of Moscow and in expensive districts of the capital city. At the same time, the threshold of 17% (the so-called “boiling point”, reflecting a sharp increase in the risks of interethnic conflicts and ghettoization of urban space) was overcome by 8 municipalities in the agglomeration. The two most noticeable areas of increased concentration of foreign migrants are identified in the south-east at the junction of Moscow and Moscow region (Lublino – Kotelniki) and in New Moscow (Mosrentgen – Sosenskoye). The calculation of the Ekkel ethnic mosaic index confirmed the presence of pronounced interethnic contact zones here. Increased index values were also noted in most central and southwest districts of Moscow, which, with a smaller proportion of foreigners living, are associated with a high density of offices, diplomatic institutions and universities. Three types of settlement patterns of national-ethnic groups of migrants, determined by the adaptive capabilities of ethnic communities, were revealed. Diffuse and relatively uniform settlement pattern is characteristic for both the most massive ethnic groups (citizens of Tajikistan, Uzbekistan and Kyrgyzstan) and the most culturally close to the local population (citizens of Ukraine and Belarus). Concentric settlement pattern (in residential areas of Moscow and satellite cities) is typical for relatively large ethnic groups coming from post-Soviet countries (citizens of Azerbaijan, Armenia, Georgia). The local settlement pattern is typical for small ethnic communities that gravitate to specific districts of the capital city.

Three-dimensional numerical analysis of the effect of foundation stiffness on soil-structure interaction

Stiffness-related geometric characteristics are closely linked to the performance of structural systems. The influence of foundation stiffness on the soil-structure interaction (SSI) mechanism was investigated by numerical modeling of different building foundations. Numerical tools (PLAXIS 3D and TQS/CAD) were used for decoupling analyses of the interaction between the structural components. Results obtained from instruments installed in a building case study were used to refine the numerical calculations. Linear elastic constitutive models and beam elements were useful in reducing computational processes and ensuring study feasibility. The simulation results provided a satisfactory representation of field observations. Interaction between piles and the environment governs the relationship between foundation stiffness and uniform settlement. Rigid pile groups are achieved with greater pile length, diameter and spacing. This study highlights the different effects of pile geometric parameters on loading and unloading rates in pillars, demonstrating that the SSI mechanism is more sensitive to less rigid foundations, particularly those with greater pile embedment. It was concluded that numerical simulations to predict settlement as realistically as possible require understanding and selecting the most appropriate model and type of calculation.

Foreign Migrants in the Moscow Agglomeration: Spatio-Temporal Analysis Based on Mobile Network Operator Data

Using mobile network operator data, the study analyzes the modern ethnic landscape of the Moscow agglomeration formed by foreign migrants. Their total number and monthly dynamics from October 2021 to October 2022 were analyzed. Foreigners’ main areas of residence were identified, the ethnic diversity of municipalities was assessed, and the main types of settlement pattern of national-ethnic communities were identified. The study showed that the total number of foreign migrants in the agglomeration reaches 1.8 mln people, or 9% of the total population, remaining almost unchanged against the backdrop of the events of 2022, including the special military operation. The share of foreigners is minimal in closed administrative-territorial units (below 3%), and it is also small in the remote parts of Moscow Region, as well as in expensive areas of the capital. At the same time, eight municipalities in the agglomeration have crossed the 17% mark, the so-called tipping point, reflecting a sharp increase in the risks of interethnic conflicts and ghettoization of the urban space. The two most noticeable areas of increased concentration of foreign migrants have been identified in the southeast at the junction of Moscow and Moscow oblast (Lublino–Kotelniki) and in New Moscow (Mosrentgen–Sosenskoe). Calculation of the Ekkel’ ethnic mosaic index has confirmed the presence of pronounced interethnic contact zones here. Elevated index values were also noted in most areas of the center and southwest of the capital, which, with a lower share of foreign residents, is associated with a high density of office buildings, diplomatic institutions, and universities. Analysis of the settlement patterns of national-ethnic groups of migrants revealed three types determined in accordance with the adaptive capabilities of ethnic communities. A diffuse, relatively uniform settlement pattern is characteristic of both the largest ethnic groups (citizens of Tajikistan, Uzbekistan, and Kyrgyzstan) and those most culturally close to the local population (immigrants from Ukraine and Belarus). A concentric settlement pattern (in residential areas of Moscow and satellite cities) is typical of relatively large ethnic groups from post-Soviet countries (citizens of Azerbaijan, Armenia, and Georgia). The local type is characteristic of small ethnic communities that gravitate towards certain areas of the capital.

Designing Foundations on Natural Soil for Specified (Uniform) Settlement

Reinforcement treatment of dredging sludge using a novel method of electro-osmosis vacuum preloading

This case study proposed a novel electro-osmosis PRD vacuum preloading method to solve dredging sludge treatment issues: difficulty in draining from soil showing large volume, non-uniform settlement, and low strength. To verify the effectiveness of the new method, four kinds of physical model tests integrating particle image velocimetry (PIV) technique of traditional vacuum preloading (VP), prefabricated radiant drain vacuum preloading (PRD-VP), electro-osmotic vacuum preloading (EO-VP), and EO-PRD-VP methods are conducted. The water discharge, average surface settlement, pore water pressure, water content, and undrained shear strength after treatment, clogging range, relationship between clogging range and water discharge rate, and relationship between clogging range and average surface settlement are investigated. For those model tests, it is demonstrated that EO-PRD-VP method has the best advantage in volume reduction, uniform settlement, and strength improvement. Water discharge is enlarged by 13–33%. The differential settlement can reach 2.3 cm, decreased by 28–56%. The undrained shear strength can reach 12 kPa, increased by 1–2 times. In addition, the clogging range development is described, for the given water discharge rate and average surface settlement, clogging range of EO-PRD-VP method is the minimum. The empirical equations between clogging range and water discharge rate, clogging range, and average surface settlement are established to predict the clogging range, which can lay the foundation for developing the consolidation theory of EO-PRD-VP method.

Creep characteristics and discharge optimization of overlying river inner dump: A case study of Yuanbaoshan open-pit coal mine in China

Overlying river can accelerate the creep of the inner dump, so to master the creep characteristics of the overlying river can provide a theoretical basis for mine safety and discharge optimization. Taking the overlying river inner dump of Yuanbaoshan open-pit coal Mine in China as the research object, a design scheme is proposed to divide it into rolling zone and non-rolling zone. Based on the creep model obtained by in-situ deformation monitoring and laboratory rheological test, the creep evolution law and deformation of overlying channel after soil discharge, slope morphology and advancing position are simulated and analyzed. The results showed that the creep variable in the (non-) rolling zone had a nonlinear upward trend with time, and the initial upward trend was large. The maximum vertical and horizontal creep in the rolling area was located in the middle and upper part of the rolling line, while the maximum vertical and horizontal creep in the dump was located in the middle and upper part of the non-rolling area, respectively. The post-construction settlement and horizontal discharging increased with the increase of the discharge height, and the convergence creep of the top ten years after construction increased approximately linearly with the decrease of the distance from the shoulder of the inner dump. The rolled sand and gravel backfill belonged to the foundation of uniform settlement deformation in general, and the change of slope shape had little effect on the deformation of the slope top in the rolled area. The geoglage elongation in the dam area met the requirements. On the premise of ensuring the stability of the dump, the slope angle of the inner dump can be appropriately increased to increase the capacity of the inner dump. The research results can provide guidance for the construction of inner dump in open pit.

Design Philosophy and Seismic Analysis of a Multi-Storey Building (B+G+10) with Flat Slabs in Seismic Zone II Using ETABS and SAFE Software

This journal paper presents the design philosophy and seismic analysis of a multi-storey building (B+G+10) with flat slabs located in Seismic Zone II. With the growing population and limited resources, vertical expansion has become a necessity. The economy's development has attracted foreign companies and innovative entrepreneurs, requiring the construction of high- end, safe workplaces. High-rise structures face challenges from wind and seismic loads, making proper design and analysis crucial for safety. The design philosophy emphasizes the use of reinforced concrete due to its versatility, durability, and fire resistance. Reinforced concrete, a composite material of concrete and steel reinforcement, ensures strain compatibility and load sharing between the materials. The paper discusses various design loads, including dead loads, live loads, wind loads, and earthquake (seismic) loads. Dead loads encompass the self-weight and permanent attachments to the structure, while live loads consider dynamic factors due to occupancy. Wind loads are assessed based on the local wind conditions, and earthquake loads are determined using seismic codes. Design principles for foundations, columns, and footings are addressed, with a focus on ensuring structural stability, safety, and uniform settlement. The depth of the foundation is calculated using Rankine's formula, considering soil properties. Column design is crucial, with short and long column classifications, and minimum eccentricity requirements are detailed. The seismic analysis of the building involves the use of ETABS and SAFE software, which enable engineers to model the structure and assess its response to seismic forces. The combination of a sound design philosophy and comprehensive seismic analysis tools ensures the building's ability to withstand various loads, thereby contributing to safety and sustainability.

Stability Analysis of Homogenous Embankment using Statistical Method

Homogeneous earth embankments are man-made or artificial structure whose construction is an important part of highway, railway and flood structure projects. Soil exhibits different properties in different places. Reinforcing the soil with Geogrid can be effectively used for improving the durability and stability of embankment, this ensures uniform settlement of embankment and result in cost effective solution. This paper aims to develop two-dimensional stability charts and correlation for slope failure (slip circle) in homogeneous soil embankment. Sensitivity analysis is also done to determine the contribution of different soil parameter. The chart and correlation developed for stability analysis can be a convenient tool for preliminary estimation of factor of safety (FOS) and possibility of failure.

Engineering Significance of Annular Raft Foundations over Solid Raft FoundationsJ

Abstract: Raft foundations play a pivotal role in distributing structural loads to the underlying soil, thereby ensuring the stability and integrity of various civil engineering structures. The choice between different types of raft foundations, such as solid and annular rafts, significantly impacts the overall performance and durability of a structure. This paper explores the engineering significance of annular raft foundations in comparison to solid raft foundations. The traditional solid raft foundation offers uniform load distribution and settlement control; however, it often encounters challenges when dealing with non-uniform soil profiles, differential settlements, and expansive soils. Annular raft foundations, a relatively innovative approach, address these challenges by featuring a central void within the raft. This void introduces a controlled differential settlement mechanism, enabling the foundation to accommodate non-uniform soil conditions effectively. Moreover, annular rafts offer improved structural performance in regions prone to ground movements, as the central void allows the foundation to adjust to soil displacements more flexibly than a solid raft. The engineering significance of annular rafts extends to their enhanced loadbearing capacity and reduction in material usage compared to solid rafts. The design of annular rafts takes advantage of the arching effect within the void, which enables the foundation to support heavier loads while minimizing the amount of concrete and reinforcement required. This not only contributes to cost savings but also aligns with sustainable construction practices by reducing the environmental impact associated with excessive material consumption.

Experimental Study and Numerical Simulation of the Effect of Rigid Pile Composite Foundations on Slab Culverts

For culverts installed in soft soil, the rigid composite pile foundation is used for soil treatment, and the stresses around the culverts are complicated. Centrifuge experiments and numerical simulations are conducted to investigate the vertical earth pressures and soil settlement over a slab culvert under high backfill in soft soil, and the foundations are treated with rigid composite piles. The influences of lateral pile length and pile spacing on the earth pressures at the top of the culvert are analysed, and they have significant effects on the vertical earth pressure coefficients. It also indicates a strong correlation between the backfill height and the vertical earth pressure coefficients. For a high-backfill culvert, there is a uniform settlement surface where the settlement of the interior and exterior soil prisms is at the same level. According to the experiments, the height of the uniform settlement surface and the vertical earth pressures decrease with increasing the lateral pile length and pile spacing. Numerical simulations were conducted using finite element software Midas GTS to evaluate the performance of the experiments. Further, recommendations for selecting an appropriate pile composite foundation for slab culvert in soft soil are provided.

Experimental study on the load bearing behavior of geosynthetic reinforced soil bridge abutments on yielding foundation

This paper presents an experimental study of the load bearing behavior of geosynthetic reinforced soil (GRS) bridge abutments constructed on yielding clay foundation. The effects of two different ground improvement methods for the yielding clay foundation, including reinforced soil foundation and stone column foundation, were evaluated. The clay foundation was prepared using kaolin and consolidated to reach desired shear strength. The 1/5-scale GRS abutment models with a height of 0.8 m were constructed using sand backfill, geogrid reinforcement, and modular block facing. For the GRS abutments on three different yielding foundations, the reinforced soil zone had relatively uniform settlement and behaved like a composite due to the higher stiffness than the foundation layers. The wall facing moved outward with significant movements near the bottom of facing, and the foundation soil in front of facing showed obvious uplifting movements. The vertical stresses transferred from the footing load within the GRS abutment and on the foundation soil are higher for stiffer foundation. The improvement of foundation soil using geosynthetic reinforced soil and stone columns could reduce the deformations of GRS abutments on yielding foundation. Results from this study provide insights on the practical applications of GRS abutments on yielding foundation.

Social Costs of Setback Distances for Onshore Wind Turbines: A Model Analysis Applied to the German State of Saxony

Wind power is a key for decarbonizing economies. Yet, wind turbines can produce negative environmental externalities. These include bird collisions and disamenities for residents. Setback distances for onshore wind turbines to settlements and bird nests are a common policy instrument to address these externalities. In this paper, we evaluate the cost-effectiveness of setback distances. We use a spatially-explicit model to investigate the social costs of different options for setbacks to settlements and red kite nests. In terms of social costs, we consider production costs and external costs associated with residents’ disamenities and red kite impacts given an exogenously set wind energy production target. The model is applied using data for the German State of Saxony. Three key results are: (1) More restrictive setbacks may increase social costs. (2) Uniform red kite setbacks reduce social costs rather than uniform settlement setbacks. (3) Differentiated settlement setbacks for different settlement types lead to substantially lower social costs than uniform setbacks.

Vertical mechanical response of axial loaded pile to tunneling-induced pile exposure

Construction of tunnels in urban cities may inevitably pass frontally through existing piles, causing pile exposure. This tunneling-induced pile exposure will cause the loss of soil resistance and redistribution of ground stress, posing a risk to the safety of existing pile. However, few studies have been carried out on such cases. This study conducted a theoretical analysis based on the two-stage method to clarify the mechanical response of pile due to tunneling-induced exposure, which calculates the tunneling induced ground settlement and the ground settlement induced pile response in two separate stages. The displacement compatibility equation of the pile at the exposure part was adjusted to account for the loss of pile-soil interaction. The results show that the overall pile deformation behaves as a uniform settlement. The additional skin friction is negative above the exposed part and positive below, resulting in the whole pile being under pressure. The axial force increases with depth above the exposed part and decreases below, while remaining unchanged at the exposed part. The pile vertical response is strongly affected by both the pile top load and the ground loss. Limiting the pile’s exposed length can significantly reduce the adverse effects of tunnel excavation.

Numerical study on heat and mass transfer mechanisms of Janus particle sedimentation considering corrosion

Janus particle is a research hotspot due to its novelty and settlement in acid liquid during wastewater treatment. Heat and mass transfer mechanisms of Janus particle sedimentation considering corrosion are numerically investigated based on immersed boundary lattice Boltzmann method. Chemical reaction heat ratio, Damkohler number, Peclet number, and particle number effects on temperature field, concentration field, Janus particle mass reduction, position, and velocity are investigated. The uniform particle has an equilibrium position of about 1/4 times the channel width for two corroded uniform particle settlement processes. The Janus particle horizontal position deviates from the uniform particle equilibrium position due to the force caused by nonuniform buoyancy and particle rotation. When the chemical reaction heat ratio is more than 1, the Janus particle horizontal position is closer to the channel centerline and has a positive deviation. However, the converse trend happens when the chemical reaction heat ratio is less than 1, and the Janus particle horizontal position has a negative deviation. The Janus particle horizontal position deviation magnitude increases with increasing Damkohler number and decreasing Peclet number. The horizontal position deviation phenomenon exists for the single corroded Janus particle and two corroded Janus particle settlement processes.

Land Subsidence Characteristics and Numerical Analysis of the Impact on Major Infrastructure in Ningbo, China

For the construction and safe operation of major infrastructure in coastal cities, the impact of regional land subsidence that has occurred or is slowly proceeding deserves attention. Previous studies have mainly focused on the surrounding land subsidence caused during construction or operation, as well as the superposition effect of land subsidence caused by groundwater extraction. However, research on the different impacts of damage due to land subsidence in the construction and operation of urban infrastructure needs to be carried out according to the actual geological environmental conditions, reflected in parameters such as the soil properties and common loads. Numerical simulation cannot fully reflect the details of reality; however, it can avoid the influence of other conditions to focus on different factors influencing land subsidence and thus highlight the contribution of a single factor influencing land subsidence. Therefore, in this paper, we adopt field measurement data and carry out a numerical simulation analysis of different influencing factors. First, taking the Ningbo Jiangdong subsidence center (now located in Yinzhou District) as an example, area growth, cumulative subsidence and the occurrence and development of the subsidence rate of a typical urban subsidence funnel area are analyzed. Then, taking the Ningbo Chunxiao–Meishan area as an example, based on the physical and mechanical characteristics of the main soil layers in the coastal reclamation area, a numerical analysis of the self-weight/backfill and surcharge consolidation settlement of the soil layer (considering the water permeability/impermeability of the bottom surface) and a numerical analysis of the nonuniform settlement caused by pile foundation engineering are carried out. Finally, the Ximenkou–Gulou area is taken as the analysis object. Numerical simulation of metro tunnel pipeline deformation is carried out considering uniform/nonuniform settlement. The results show that the comprehensive prohibition of groundwater exploitation is beneficial to slow the land subsidence rate, while the sedimentation of silty clay in Layer 4 (muddy clay) is the largest among all the soil layers. Compared with uniform settlement, nonuniform settlement is more likely to cause connection failure between tunnel segments. The above research results can provide references for the prevention and control of land subsidence and thus the safe operation of major infrastructure.

Mechanical Behavior of Soil Foundations Reinforced with Geosynthetics Exposed to Normal and Reverse Fault Ruptures

Surface fault ruptures damage structures which are located at the intersecting zones of active faults. It is essential to consider the undesirable effects of surface fault ruptures when designing structures. Geotechnical measures such as reinforced soil foundations effectively mitigate the hazards related to surface faults. The present work conducted a series of tests on foundations reinforced with geosynthetics, including geogrids, geocells and geogrid-geocell layers. These tests simulated the behavior of 1.5 m-wide strip footings located in 6-m thick alluvium that had been displaced 60 cm. A total of 12 disparate tests in terms of the number and type of reinforcement were conducted at a scale factor of 10. Image analysis of the results indicated desirable behavior for reinforced soil foundations in terms of reduced angular distortion, uniform settlement and deviation of the fault path. For normal fault rupture, the angular distortion of foundations reinforced by one geogrid layer, one geocell layer, one geogrid-geocell layer or two or three geo-grid layers decreased by 60%, 30%, 70%, 80% and 80%, respectively. These results also revealed that an increase in the number of geogrid layers to more than two layers caused an insignificant decrease in angular distortion. The decrease in angular distortions observed for soil foundations reinforced by one geogrid layer, one geocell layer and one geogrid-geocell layer were 7%, 16% and 40%, respectively, for reverse faulting. The performance of a reinforced soil foundation subjected to normal faulting was more acceptable than that for reverse faulting.

Application of scanning electron microscopy and IR spectroscopy for a timely evaluation of the morphology and chemical composition of bacterial films during batch cultivation

Bacteria most commonly exist in nature in the form of bacterial biofilms, i.e. associations of cells attached to a substrate surrounded by a polymer matrix. Research into biofilm formation and functioning is fundamental to the management of microbial associations in ecology, biotechnology and medicine. This task requires the development of analytical approaches capable of providing timely information throughout the life cycle of microbial communities at the same time as maintaining their intact structure. In this paper, we apply scanning electron microscopy and IR spectroscopy as rapid methods for analysing microbial biofilms. To this end, the growth kinetics of a Bacillus subtilis culture cultivated on a solid substrate for 24 h was comparatively studied by the methods of classical microbiology and biochemistry, electron scanning microscopy and Fourier-transform IR spectroscopy. The biofilm morphology was found to vary from a uniform settlement of planktonic cells over the substrate surface at the initial stage of growth (6 h) followed by the accumulation of the extracellular matrix and the formation of microcolonies at the exponential and stationary stage (12–18 h) and a gradual depletion of the matrix at the stage of cell death (24 h). The results of IR spectroscopy were established to agree well with those of biochemical studies, thereby demonstrating the potential of the method for a timely evaluation of the accumulation of proteins, polysaccharides and nucleic acids and for obtaining information about their structural state in the studied biofilm. It is concluded that scanning electron microscopy and Fourier-transform IR spectroscopy can be used for obtaining complementary information about the morphology and chemical composition of microbial biofilms during their cultivation.

ПРАВОВЫЕ ОСНОВЫ ДЕМОГРАФИЧЕСКОЙ ПОЛИТИКИ ДЛЯ ГАРАНТИРОВАНИЯ КОМФОРТНОГО ПРОЖИВАНИЯ

The relevance of the research topic lies in the obvious need to address the issue of uniform settlement of people across the territory of Russia. This problem is not new, since there are and are being implemented various state programs related to the provision of preferences to citizens and organizations for settling the Far East and other territories remote from the center of the country, there are special economic zones, etc. Nevertheless, the bulk of the population continues to remain in large cities, which have become such largely due to the proximity of state power and, accordingly, officials with whom it is necessary to constantly maintain various kinds of relationships and often just personal contact. With the development of various aspects of entrepreneurial activity, including with the participation of large businesses, this paradigm must change. This study analyzes the legal framework for the implementation of this kind of activity. The purpose of this study is to consider the legal framework for the implementation of demographic policy in terms of the rational distribution of the population across the territory of Russia to create comfortable living conditions for citizens. The achievement of the designated goal is the development of proposals for the transformation of legal regulation and the practice of its application to intensify the uniform settlement of the country's inhabitants. For the preparation of this work, general philosophical, general scientific and private law methods of scientific research were used. The result of the work done is a number of proposals for the law-making and organizational nature of the use of special legal regimes in certain territories and the actualization of the practice of single-industry towns that are formed around the city-forming enterprises and similar industries. Output. It seems necessary to streamline the normative legal regulation of issues related to the establishment of special regimes in certain areas, by adopting a "territorial code" or another document similar to it. It is necessary to partially transform the current legislation in the area under consideration and systematize the organization of its implementation.
