Natural and anthropogenic factors that determine the activity of geological processes of the Abakan agglomeration

Relevance. As a result of the construction and operation of buildings and structures within the Abakan agglomeration, there is an activation of existing and the formation of new engineering and geological processes accompanied by accidental destruction of constructions. In order to minimize economic and socio-environmental damage, timely development of scientifically sound urban planning and architectural planning solutions is necessary. It would take into account the results of design studies of engineering protection of the territory from dangerous manifestations of engineering and geological processes. Generalization of the available survey results in order to typify the engineering and geological conditions of the urban area will optimize the construction development of urban areas, develop reliable schemes of engineering protection against the manifestations of dangerous engineering and geological processes. Aim. To establish natural and anthropogenic factors that determine the activity of dangerous geological processes in the territory of the Abakan agglomeration. Methods. Collection, systematization and analysis of available territorial geological, hydrological, hydrogeological, environmental information, results of engineering surveys. Results and conclusions. At a qualitatively new level, a set of maps has been compiled on the factors that determine the development of dangerous geological processes. The authors have carried out a GIS analysis of morphometric indicators of the relief of the agglomeration territory: maps of the steepness and exposure of the slopes were constructed. The analysis of the collected data made it possible to establish the regional characteristics of the components of the geological environment and propose a zoning scheme for the territory for its construction development and engineering protection. The authors identified four taxa during zoning: territories favorable for construction that do not require significant engineering training; territories conditionally favorable for construction, requiring preliminary engineering training; territories conditionally unfavorable for construction, requiring significant costs for engineering training; territories unfavorable for construction. The boundaries of the taxa are based on the analysis of the geomorphological features of the territory. The conducted research was performed for the agglomeration territory for the first time.

Selecting Erosion- and Deposition-Dominated Zones in the Jezero Delta Using a Water Flow Model for Targeting Future In Situ Mars Surface Missions

Identifying surface sites with significant astrobiological potential on Mars requires a comprehensive understanding of past geological processes and conditions there, including the shallow subsurface region. Numerical modelling could distinguish between regions dominated by erosion and those characterized by sediment accumulation in ancient wet environments. The target area of Jezero Crater is relatively well explored and thus is an ideal site to evaluate model calculations; however, important works are still missing on expectations related to its shallow subsurface . In this work, the best available approaches were followed, and only surface morphology was considered (supposedly formed by the last fluvial episode). The shallow subsurface became an important target recently, and this model could provide new inputs in this area. Erosion–accumulation models are suitable for terrestrial surface features, but few have been applied to Mars. This work addresses this challenge using the SIMWE (SIMulated Water Erosion) model on the Jezero Crater delta, the landing site of the Perseverance rover. For calculations, the average grain size according to the THEMIS TI data was applied to the target area. The flow depth varied between 1.89 and 34.74 m (average of 12.66 m). The water-filled channel width ranged from 35.3 to 341.42 m. A flow velocity of 0.008–11.6 m/s, a maximum erosion rate of 5.98 g/m2/h, and a deposition 4.07 g/m2/h were estimated. These calculated values are close to the range of estimations from other authors assuming precipitation of 1–20 mm/h and discharges of 60–400 m3/s. The model was able to distinguish between erosion- and accumulation-dominated areas about 1 m above Jezero Crater’s delta that are not visible from above. This model helps to identify the accumulation-dominated areas with the finest grain size with good preservation capability for the shallow but invisible subsurface.

Based on Flac3D Research and Analysis of the Mining Pressure Development Law in the Top Coal Section of the Roadway Support of the Working Face Transport

Top coal supporting roadway is widely used in the transportation roadway of thick coal seam face, which can not only increase the coal extraction rate but also reduce the driving cost. Based on the engineering geological conditions of the transportation lane of the working face of Zhongma Cun mine, the law of mine pressure development in the roadway of the top coal section is studied and analyzed based on Flac3D and field monitoring methods. The numerical simulation analysis shows that when the working face is pushed to 55m for the first time, the displacement of the area affected by the leading abutment pressure and the surrounding rock on the mining side of the roadway reaches the peak value, and the step distance of the first time is 55m. According to the analysis of stress monitoring data of single pillar and roof anchor cable on site, the first pressure occurs when the working face advances to 51m, which is consistent with the numerical simulation conclusion.

Experiment Study on Rock Mass Classification Based on RCM-Equipped Sensors and Diversified Ensemble-Learning Model

The geological condition monitoring and identification based on TBM-equipped sensors is of great significance for efficient and safe tunnel construction. Full-scale rotary cutting experiments are carried out using tunnel-boring machine disc cutters. Thrust, torque and vibration sensors are equipped on the rotary cutting machine (RCM). A stacking ensemble-learning model for real-time prediction of rock mass classification using features of mathematical statistics is proposed. Three signals, thrust, torque and a novel vibration spectrogram-based local amplification feature, are fed into the model and trained separately. The results show that the stacked ensemble-learning model has better accuracy and stability than any single model, showing a good application prospect in the rock mass classification.

GROUNDWATER POLLUTION SOURCE USING PRINCIPAL COMPONENT ANALYSIS IN GUELMA PLAIN, NORTHEAST ALGERIA

This study was conducted in the agricultural region of Guelma, located in northeastern Algeria, where groundwater is the main source of water for human consumption, agriculture, and industry. The objective was to characterize groundwater quality and identify potential pollution sources using multivariate statistical methods, including Principal Component Analysis (PCA), correlation matrix, and the Piper diagram. The analyses revealed strong correlations between certain ions, such as sodium and chloride, suggesting carbonate dissolution processes, such as calcite and dolomite, leading to increased water hardness. The Piper diagram allowed for the classification of water types based on the relative concentrations of major cations (Ca²⁺, Mg²⁺, Na⁺+K⁺) and anions (Cl⁻, SO₄²⁻, CO₃²⁻+HCO₃⁻), showing a predominance of mixed hydrochemical types influenced by both natural and anthropogenic processes.PCA then simplified the interpretation by identifying the most influential variables that could serve as key indicators for the continuous monitoring of water quality. Overall, the results indicate that groundwater chemistry in this region is strongly influenced by human activities and local geological conditions, highlighting the need for sustainable management and continuous monitoring to protect this vital resource.

Estimasi Cadangan Batugamping Menggunakan Block Model Berdasarkan Metode Interpolasi IDW pada IUP OP 231 Karangkemojing

The increasing development of infrastructure development has an impact on the increase in cement demand. Cement is used as the main raw material in making concrete and other construction materials. Therefore, limestone mining as a raw material for cement is also increasing. One of the areas that has prospects for limestone mining is IUP OP 231 Karangkemojing which is still in the exploration stage. The purpose of this study is to determine the geological and geomorphological conditions of the study area, determine the amount of limestone reserves, and determine the estimated mine life based on production targets. The methods used in this research are field observation and laboratory analysis including petrographic analysis and X-Ray Fluorescence (XRF) analysis. Furthermore, the calculation of limestone reserves was carried out using block modeling and the Inverse Distance Weighting (IDW) interpolation method processed using Surpac software. Based on field geological mapping, the research area is included in the wavy hilly and steep hilly structural landforms, which consist of two lithological units, namely sandstone and claystone intermixture units and limestone units. The results of the calculation of limestone reserves in the study area were obtained at 61,444,362 tons with an estimated mine life of about 24 years and 6 months.

EVALUATING CUT SLOPE STABILITY DURING RAINFALL EVENTS IN HA GIANG CITY, VIET NAM

The main objective of the present study is to investigate the mechanism of triggering slope failures during extreme rainfall events under the climatic and geological conditions of Ha Giang city, Viet Nam. For this purpose, the specific research objectives of this paper were based on the analytic results of the geotechnical properties of the soil samples. The pore water pressure distribution on a slope was changed by the influence of rainfall. In order to analyze the stability of the cut slopes, the two modules SEEP/W and SLOPE/W in the GEOSTUDIO 2012 software were employed and integrated. First, the initial steady seepage condition was used to assess the effect of extreme rainfall for a transient seepage. Second, the soil sample properties and some features were assigned in the slope stability model, such as unit weight, cohesion, internal friction angle, and hydraulic functions, and then the achieved transient pore water pressure regime was used as the input parameter to calculate the factor of safety (FS) on cut slopes. Finally, the relationship between the changing of the FS over time and the hourly rainfall intensity that resulted in slope failure were evaluated. In summary, the slopes in Ha Giang city can be stable under normal conditions, but their stability is always a dilemma for local authorities due to the influence of intense rainfall.

Soil Displacement of Slurry Shield Tunnelling in Sandy Pebble Soil Based on Field Monitoring and Numerical Simulation

Due to its inherent advantages, shield tunnelling has become the primary construction method for urban tunnels, such as high-speed railway and metro tunnels. However, there are numerous technical challenges to shield tunnelling in complex geological conditions. Under the disturbance induced by shield tunnelling, sandy pebble soil is highly susceptible to ground loss and disturbance, which may subsequently lead to the risk of surface collapse. In this paper, large-diameter slurry shield tunnelling in sandy pebble soil is the engineering background. A combination of field monitoring and numerical simulation is employed to analyze tunnelling parameters, surface settlement, and deep soil horizontal displacement. The patterns of ground disturbance induced by shield tunnelling in sandy pebble soil are explored. The findings reveal that slurry pressure, shield thrust, and cutterhead torque exhibit a strong correlation during shield tunnelling. In silty clay sections, surface settlement values fluctuate significantly, while in sandy pebble soil, the settlement remains relatively stable. The longitudinal horizontal displacement of deep soil is significantly greater than the transverse horizontal displacement. In order to improve the surface settlement troughs obtained by numerical simulation, a cross-anisotropic constitutive model is used to account for the anisotropy of the soil. A sensitivity analysis of the cross-anisotropy parameter α was performed, revealing that as α increases, the maximum vertical displacement of the ground surface gradually decreases, but the rate of decrease slows down and tends to level off. Conversely, as the cross-anisotropy parameter α decreases, the width of the settlement trough narrows, improving the settlement trough profile.

Individual-portal support with a pre-tensioned canopy for a coal mine roadway junction

Abstract This paper presents an alternative model of individual-portal support structure with a pre-tensioned canopy for coal mine roadway junctions in the geological and mining conditions of underground mines in Vietnam. The aim of the research is to determine the bearing capacity of the individual-portal support structure with various configuration. For this purpose, an analysis of the rock mass behaviour around the three-way roadway junction was carried out using the difference element method-based programme (FLAC3D). Additionally, other analysis of the bearing capacity of the selected individual-portal support structure was also conducted using the finite element method-based programme (COSMOS/M). The geological and mining conditions of Vietnamese mines were taken into account during performing these analyses. Based on the results, the optimal individual-portal support structure was proposed for the roadway junctions driven in the geological and mining conditions of underground mines in Vietnam.

NON-DESTRUCTIVE METHODS OF ESTABLISHING A CAUSE-AND-EFFECT RELATIONSHIP BETWEEN WATER SUPPLY NETWORK ACCIDENTS AND THE CONDITIONS FOR PRESERVING ARCHITECTURAL HERITAGE

Accidents on water supply networks have the most significant negative consequences on the state of the historical and architectural heritage, which was formed over many centuries. The paper analyzes the cause-and-effect relationship between accidents of water-carrying networks and the conditions of architectural heritage preservation using the example of the Kyiv-Pechersk Lavra. The results of determining waterlogging zones and their factors by non-destructive monitoring methods on the territory of the Metropolitan Garden of the Upper Lavra are given. This area combines complex engineering and geological conditions and technogenic mastering, creating conditions for developing dangerous engineering and geological processes and emergency situations. In terms of danger, the garden’s territory belongs to unstable areas for preserving historical monuments of the UNESCO world heritage. The last accident on the water supply networks occurred in October 2022. It caused sinkholes on the surface, rising groundwater levels, significant destruction of an underground structure of historical importance – the Metropolitan Cellar. The research was carried out using the methods of electrotomography and natural electric field. The results of electrotomography were interpreted using two- and three-dimensional models. The existence of an anomalous dome (soils of low resistance), which is observed in the central part of the site, is probably the focus of waterlogging of the soil massif as a result of an accident on the heating network. The analysis of the adapted 3D model based on the results of non-destructive methods of monitoring the geological environment made it possible to indirectly establish the places of unsatisfactory technical condition of engineering networks (cold water supply), where a wetted section with low values of apparent resistance was recorded. Research has confirmed the presence of an inflow of man-made waters (leaks) from main water supply networks in the western part of all profiles as a constant source and factor of waterlogging of the array of soil bases of architectural monuments – Monastyrski walls, Kushnyka tower, etc. Based on the research results, the need to develop compensatory measures to strengthen part of the fortress walls was proposed, and a safe distance for moving networks from historical objects was substantiated to preserve them.

Engineering-geological conditions of the Shirvan Steppe of the Kura-Aras Lowland of Azerbaijan Republic and the influence of the Upper-Shirvan Canal on it

Since 1950, the area of the Shirvan Steppe has been subject to numerous ameliora- tive measures, as well as the construction of a number of hydrotechnical facilities. Natural and anthropogenic effects have altered the level of groundwater, mineralization level, chemical composition, engineering-geological conditions, soil salinity, and chemical composition of soils. In order to reflect the engineering-geological conditions of the Shirvan Steppe, geological-hydrochemical sections were created in two directions, in the direction of groundwater flow (I-I) and the direction across the flow of groundwater (II-II). The analysis consid- ered the engineering-geological, physical-geographical, geomorphological, geological, and other conditions of the studied area before and after construction of the Upper Shirvan Canal. Along the route of the Upper Shirvan Canal, the research revealed the main soils as follows: loam, clay, gravel-pebble, sand, and loamy sand. The engineering-geological parameters such as minimum moisture capacity, hygroscopic moisture, volume, weight, density, porosity, and granulometric composition of the soils along the route of Ujar, Kurdamir, Goychay regions, and the Upper Shirvan Canal have been determined. Over the 70-year continuous operation of the Upper Shirvan Canal, settlements in the area of its influence expanded, thereby increasing the loading on the canal beyond the norm. As a result of damage to the concrete coatings of the canal, the quality of operation has decreased, some infrastructure located on it has ceased to function, and water losses from the canal have increased. In such conditions, it is important to study the formation of engineering-geological conditions resulting from natural and anthropogenic effects and to take preventive measures against negative impacts. During the reconstruction and subsequent operation of the canal to provide water to the newly irrigated land areas in the Shirvan Steppe, there should be taken into account the technogenic effects on the geological environment and relevant proposals of important scientific and practical importance regarding the reconstruction project.

Coulomb Stress Changes in the 2004 Aceh Earthquake on the Mount Sibualbuali and Mount Lubukraya

The great Aceh earthquake on December 26, 2004, had a magnitude of 9.2 Mw for 10 minutes with coordinates 3,316°N 95,854°E. had a tremendous impact on changes in geological conditions and disasters in Aceh and Asia, especially Southeast Asia and South Asia. Changes in geological conditions have resulted in Aceh and its surroundings becoming more prone to earthquakes, including volcanoes in North Sumatra. This research aims to determine the value of changes in coulomb stress that occur on Mount Sibualbuali and Lubukraya. This research uses the coulomb stress method presented in Coulomb 3.4 software. This research produces positive coulomb stress changes in 2021 which are marked by the red lobe, namely 0.197 bar on Mount Sibualbuali and 0.187 bar on Lubukraya. The highest increase in chwerees in coulomb stress was in 2015, namely 0.319 bar in Sibualbuali and 0.262 bar in Lubukraya. This research also resulted in the highest coulomb stress changes at a depth of 90-100 km so that it does not affect the volcanic activity of the two mountains.

Determining the Stability of a Potentially Dangerous Landslide Slope

Abstract Due to the acceleration of construction of civil, industrial and infrastructure facilities in our republic and the expansion of their area, the construction of many facilities is carried out in mountainous, and foothill areas with complex relief and geomorphological conditions, which in most cases are potentially dangerous landslide slopes. To protect these facilities from the negative impact of dangerous geological, natural-technogenic, and anthropogenic processes, to assess the risks arising from the impact of these processes on building structures, to promptly prevent negative phenomena and dangerous situations, to assess the engineering and geological conditions of the construction area to determine the stability of the slope, conducting research in these areas is of great practical importance. Mountainous regions are characterized by the complexity and diversity of geological, hydrological, hydrogeological, and tectonic conditions. Landslides are the most common natural and man-made processes that pose a threat to the safe operation of infrastructure facilities, civil and industrial construction in mountainous and foothill areas. In addition to infrastructure facilities, landslides can destroy vegetation, destroy the habitat of fauna, and also destroy fertile soils located in the area of their activity (Nikolic, 2015; Krivoguz & Bespalova, 2020). The main objective of this article is to apply the results of practically implemented and verified studies in other territories of our republic with similar geomorphological structure and engineering-geological conditions, to correctly assess the negative manifestations caused by landslides and other man-made and anthropogenic impacts, as well as to calculate the stability of the slope and scientifically and technically substantiate measures for engineering protection against landslides.

Characteristics of debris flow dynamics and prediction of the hazardous area in Bangou Village, Yanqing District, Beijing, China

Abstract Debris flow is one of the most common types of geological disasters in China. Owing to the influence of topography, geomorphology, geological conditions, human activity, and rainfall debris flow disasters frequently occur in the mountainous areas of Beijing. The research on debris flow in the Beijing area focuses on rainfall and risk evaluation, material sources, and early warning and prevention of debris flow. However, there are few studies on the development characteristics of single-gully debris flow and the prediction of hazardous areas in the Beijing area. Therefore, we chose the debris flow of Bangou Village in Yanqing District of Beijing as the research object. We analyzed the recharge conditions in the ditch domain and predicted the extent of the hazardous area around the gully, providing suggestions for control measures. The dynamic reserves of the loose deposits in the debris flow gully, currently in the development stage, were estimated as 15.48 × 104 m3, representing four supply sources: artificial deposits, alluvium and diluvium, residual slope deposits, and collapse. The peak flow is 24.49 m3/s for a 10-year rainfall event, 27.64 m3/s for a 20-year rainfall event, 31.79 m3/s for a 50-year rainfall event, and 34.93 m3/s for a 100-year rainfall event. The total amounts of solids washed out by a debris flow from the preceding events are 0.70 × 104 m3, 0.79 × 104 m3, 0.91 × 104 m3, and 1.00 × 104 m3, respectively. The size of the debris flow is small, with a maximum hazardous area of 0.2810 km2. We conclude that a small debris flow outbreak in the Bangou Village gully is possible. We expect that the results of this study will provide basic information and help improve debris flow research in Beijing.

Microzonation Approach for Analyzing Regional Seismic Response: A Case Study of the Dune Deposit in Concón, Chile

Urban areas located on complex geological formations, such as dune deposits, require detailed seismic risk assessments that extend beyond standard seismic codes. This study focuses on the city of Concón, Chile, where a significant portion of the urban area is situated on a coastal dune deposit. The research integrates seismic microzonation with a three-dimensional finite element model (3D FEM) to comprehensively evaluate the regional seismic response. Field data from 208 strategically distributed points were collected and combined with geotechnical and geomorphological information to construct a detailed 3D model of the region. This model allowed for the simulation of seismic behavior under various conditions, highlighting the limitations of general seismic codes in capturing local variations in seismic response. The results underscore the importance of considering local geological conditions in structural design, particularly in areas with irregular topography and complex subsurface conditions. This study concludes that incorporating microzonation into urban planning and seismic analysis can significantly enhance infrastructure resilience and disaster preparedness, providing a replicable approach for other cities facing similar geological challenges.

Study on the structure and strata behavior regularity of repeated mining overburden of close-distance shallow buried coal seam group

This paper studies the collapse structure, plastic failure regularity, and overburden movement regularity in the mining process of the Shallowly Buried Coal Seam (SBCS) group in the Yulin area using physical similar material simulation, computer numerical simulation, and theoretical analysis. The objective of the present article is to explore the strata behavior regularity of the SBCS group, taking the engineering geological conditions of Hongliulin Coal Mine as the sample. According to the results, when the lower coal seam of the SBCS group is mined, the initial stress step increases, and the periodic stress step decreases compared to the upper first coal seam. During the mining of the lower coal seam, there is an extreme collapse span in the interlayer rock formation: the process induces the activation of the collapsed roof in the goaf of the upper coal seam, and the overall sinking phenomenon occurs. The dynamic stress is obvious. The roof stress is significant in passing through the upper coal seam's residual coal pillar (CP) into the lower coal seam. The CP is at a certain distance, and the residual CP is violently unstable and sinks the strata behavior regularity. The interlayer rock layer forms an inclined shear staggered fracture zone along the coal wall. The research results provide a theoretical method for controlling mine stress and green and safe mining in the SBCS group of coal production enterprises.

Mechanical Performances of Concrete-Filled Steel Pipe Composite Segments in Complex Geological Conditions

When shield tunnels are under complex geological conditions, tunnel damage, decreased structural performance, and shield tunnel deformation and destruction may occur. Therefore, a new type of composite segment and combined splicing joint were suggested and experimentally investigated in this study. According to the test results, the new composite segment effectively enhanced the load capacity of the segment, and the yield and ultimate loads of the segment were increased. Compared with the reference specimen, the ultimate load capacities of the proposed segments with different numbers were 23.8%, 50.0%, and 64.3% greater. Moreover, the combined splicing joint enhanced the initial bending stiffness and load capacity of the segment joint, reduced the opening displacement, and improved the rotational stiffness of the segment joint. The addition of a plug-in joint at the segment joint increased its load capacity by approximately 25%. A parametric study showed that the number and posit ion of the plug-in joint clearly affected the load capacity of the segment joint. In addition to the above test results, reasonable theoretical formulas for the new composite segment and combined splicing joint are given in this paper.

Engineering geological investigation of Gololcha dam for evaluation of leakage and abutment slope stability, Eastern Ethiopia

The Ethiopian economy is primarily dependent on agriculture, making the construction of water harvesting facilities, such as dams, crucial for improving the productivity of this sector. The ongoing construction of the Gololcha dam on the Kurkura River located in Eastern Ethiopia aims to enhance irrigation schemes in the region. However, the dam site's complex geological and structural conditions pose challenges related to leakage and slope instability. Hence, this study focuses on addressing the abutment slope stability and leakage condition of this dam. This study employed kinematic analysis and the Limit Equilibrium Method (LEM) to assess slope stability. Additionally, engineering geological mapping, discontinuity surveys, seismic refraction tomography (SRT), and in-situ permeability testing were used to evaluate the leakage condition of the dam site. Notably, the permeability and SRT survey results identified potential leakage zones to the depth of 35, 30, and 35 m at the left, right, and central foundations of the dam, respectively. The kinematic method revealed one planar and two wedge modes of failure in the slope section covered by slightly weathered and fractured basalt rock at the right abutment. Further stability analysis of these two modes of failures via LEM analysis indicated slope instability under saturated conditions, emphasizing the role of pore water pressure. Furthermore, LEM modeling was directly utilized using the Slide 6.0 software to analyze the slope stability condition of the left abutment of the dam. This modeling also uncovered instability under saturated conditions. Based on the study findings, this study recommended curtain grouting to address potential leakage, as well as slope flattening and removing unstable rock wedges and loose material to stabilize unstable slope sections.

Optimization of Embodied Energy and Construction Cost of Low-Income Housing in Urban India

India is the most populous country in the world, having a population of 1.42 billion in 2022. It is urbanizing rapidly, with the present urbanization level at about 35%, which is expected to reach about 40% by 2030. There was an estimated demand of 11.22 million homes in urban India in 2017, of which 95% was in the affordable housing sector. This demand is expected to increase with the current urbanization trends. The Indian government is promoting the construction of millions of affordable houses under its ambitious Prime Minister’s Housing Program. These houses are planned, designed, and constructed using local materials and techniques, considering local climatic, geological, hazard, and socio-economic conditions. We examined the 30 most commonly applied housing typologies to determine which typologies and materials have minimum embodied energy and construction costs. The results indicate that load-bearing housing construction of up to three stories, with a plinth–carpet area ratio of 1.31, constructed with any of the blocks-based masonry techniques, has the lowest embodied energy and construction cost, and houses with a plinth–carpet area ratio of 1.51 have the highest. Further, houses constructed with Hollow CC block masonry have the lowest embodied energy, and HF Fly Ash block-based masonry has the lowest construction cost.
