Development of an intelligent geographic information system for mountain roads monitoring: Ground data collection and analysis

This study examines the development of an intelligent geographic information system for mountain road monitoring. To make well-informed and timely management decisions in the planning, construction, and maintenance of mountain roads, and to anticipate potential critical situations and their effects on road conditions, it is imperative to employ modern methodologies. This study involves data collection from a specific section of a mountain road situated near Almaty, Kazakhstan. We gathered data on the road section through visual assessment, measurements of the coefficient of adhesion, and the acquisition of material samples from the structural layers of the roadbed. Based on the visual assessment and surface adhesion measurements, it became evident that the deformation of the studied road section, which includes a network of cracks and "non-standard" transverse cracks, is attributed to mountain mass shifts and water flows from slopes. Laboratory analysis of the collected samples revealed that excessive water saturation could result in cracks during freeze-thaw cycles, while a low resistance coefficient would lead to softening during humid conditions. An Intelligent Geographic Information System (IGIS) will incorporate the collected data alongside open remote sensing and weather data. The objective is to utilize this integrated system in the future for forecasting road conditions and maintenance requirements for similar roads in mountainous regions of the area. The measurements are carried out according to the state standards. That makes the system useful for government management purposes.

Effects of freeze-thaw cycles on fatigue performance of asphalt mixture and a fatigue-freeze-thaw damage evolution model

To study the effect of freeze-thaw (FT) cycles on the fatigue performance of composite crumb rubber modified asphalt mixtures (CCRMA), a semicircular bending fatigue test based on the digital image correlation technique (DIC) was used to measure the fatigue life (Nf) of CCRMA and SBS modified asphalt mixtures (SBSMA) and the horizontal strain (Exx) of the DIC deformation field under repeated loading. The variation laws of Nf, Exx and the damage factor (D) defined based on Exx were analyzed under FT cycle conditions. In addition, considering the important influence of FT cycles on the Nf and damage evolution characteristics of asphalt mixtures, based on the classical Chaboche damage evolution model, the influence of FT cycle was considered, a fatigue-freeze-thaw damage evolution model that reflects the effects of FT cycling variables and stress levels on asphalt mixtures was constructed. The results indicate that the Exx peak of asphalt mixture shifts forward with increasing FT cycle number. After 20 FT cycles, the Nf of CCRMA decreased by 73.4 %, 62.1 %, and 75.1 %, while that of SBSMA decreased by 76.5 %, 58.6 %, and 74.6 % at stress ratios of 0.2, 0.3, and 0.4, respectively. The fatigue-freeze-thaw damage evolution model predictions were in agreement with experimental results, with the goodness of fit (R2) of all Nf prediction models being greater than 0.9. With the exception of a few outliers, the relative error between the measured and predicted Nf for the two asphalt mixtures was within 15 %. This indicates that the model can effectively predict the Nf and damage evolution laws of asphalt mixtures at different stress levels after an arbitrary number of FT cycles. The related research results provide a theoretical basis for predicting the Nf of new roads in cold regions under FT cycles.

Raising international issues related to road maintenance and repair. Road damage occurring in various countries, including cracks, potholes, and surface deformation, significantly impacts transportation safety and efficiency. Many roads in certain regions experience damage such as cracks, potholes, and surface deformation due to increased traffic loads and extreme weather conditions. The purpose of this paper is to analyze road damage in Karamat Village according to Bina Marga standards, to identify and understand the causes and effects of such damage. Primary data is the data collected from field observations at the study site, referred to as primary data or first-hand data. The road damage found on Pajaten road in Karamat Village, Majalengka Regency includes patches, cracks, disintegration, potholes, and waves. The purpose of routine maintenance is to improve the surface layer quality without increasing structural strength. The Pajaten road section in Karamat Village, Majalengka Regency, has conditions of loose stones, cracks, patches, potholes, and waves. The Directorate General of Highways states that the calculation results have a priority order of 10, placing it in the priority group > 7. According to Bina Marga, road damage is addressed through a routine maintenance schedule. Patching is the recommended and suggested method for repairing cracks, ruts, and collapses on roads.

Road Site Inspection and Measures to Avoid Further Deformation

Strength and stability of the roadbed and engineering structures in permafrost conditions and deep seasonal freezing of soils always remain complex scientific, technical and technological problem in construction and reconstruction of roads in northern regions. Particularly important is the spread of subgrade subsidence during construction and further operation and maintenance of roads in these regions. The road destruction is mostly caused by both global warming and geological and hydrogeological conditions.To prevent the deformation development, it is necessary to provide a number of special engineering measures to prevent thawing of permafrost soils or strengthen supra-permafrost layers of foundations. The purpose of the work is to study methods for eliminating deformation of the road bed in permafrost and choosing the main method for eliminating subsidence of the road.The article discusses several ways to solve the problem of eliminating subsidence on of the federal highway. Options for reconstruction of the roadbed are considered. These are different methods of thermal stabilization, i.e., horizontal (sloping) thermal stabilization system with inclined thermal stabilizers, temporary vertical thermal stabilizers for pre-construction freezing of foundation soils, and hybrid thermal stabilization system (horizontal and vertical thermal stabilizer in one product). A method is proposed for stabilizing the road base by installing soil-cement piles. The main advantages of and disadvantages the methods are noted and cost assessment is made. A conclusion is drawn on the effectiveness of different methods to restore the subgrade structure in order to ensure the road base stability. The main method is elimination of subsidence by stabilizing the road base with installation of soil-cement piles.

Dirty road extraction from GF-2 images by semi-supervised deep learning method for arid and semiarid regions of southern Mongolia

ABSTRACT The uncontrolled proliferation of natural roads in arid regions has exacerbated regional land degradation and desertification, presenting substantial challenges to their accurate mapping owing to their dynamic and obscure features. Moreover, the high cost of data annotation restricts the availability of comprehensively labelled datasets, which are essential for advanced remote sensing processing and natural road detection. This study dedicated to implement a semi-supervised deep learning method for dirty road extraction in southern Mongolia. A new thematic semantic segmentation dataset of natural roads was established firstly to address scarcity of annotation datasets this region. A semi-supervised UniMatch structure was designed consequently. Operating with high-resolution GaoFen-2 images, this approach minimises the need for extensive manual annotation, achieving an IOU of 73.51% and MIOU of 86.37%. This method significantly reduces labour and time costs associated with manual and fully supervised methods. These observations provide a valuable data source and methodology for addressing natural road expansion in arid regions. They can aid governments in evaluating transportation infrastructure in remote areas, and analysing dirty road traffic impact on environment.

Numerical analyses on the spatial-temporal thermal influence range of embankment in the Qinghai-Tibet Engineering Corridor

The density of linear engineering projects within the Qinghai-Tibet Engineering Corridor has increased, and the study of the thermal influence range of a single linear engineering project has become more important. This paper employs the finite difference method to investigate the influence of embankment size, mean annual ground temperature (MAGT), and construction time on the spatial-temporal evolution of the embankment's lateral and vertical thermal influence range. Additionally, a parameter sensitivity analysis of the lateral and vertical thermal influence ranges throughout the entire service life of the embankment is conducted. The results indicate that under the same service time, the lateral-vertical ratio (Lc/D), as well as the lateral thermal influence range (Lc) and the vertical thermal influence range (D), increase linearly with increasing embankment height and pavement width. The Lc/D increases with increasing MAGT, but the Lc and D decrease with increasing MAGT. The Lc/D, the Lc, and the D are not significantly affected by construction time. During the 50-year service life of the embankment, the most significant factor impacting the Lc is the pavement width, and the MAGT is the most significant factor impacting the D. The results are expected to serve as a guide for the design and construction of roads in the permafrost regions of the Qinghai-Tibet Plateau.

Innovative high-strength, high-permeability concrete for large-scale applications in permeable subgrade of highway tunnel

The durability of concrete roads in mountainous regions may be reduced due to underground water infiltration and surface water erosion within highway tunnels. A promising solution is the use of pervious concrete as a drainage subgrade layer to drain away the water, and then to prevent water-induced pavement damage of pavement. For pervious concrete to be an ideal drainage layer for high-traffic loads, it must have compressive strength and permeability coefficient exceeding 25 MPa and 15 mm/s, simultaneously. However, traditional pervious concrete tends to emphasize either in high-strength or high-permeability, depending on its porosity. This study introduces an innovative proportion design method of pervious concrete, which enables higher compressive strength and permeability coefficient by adjusting its skeleton structure, and thus catering to high-traffic load applications. In addition, the workability and setting time of pervious concrete were optimized according to the local environmental conditions, facilitating large-scale and efficient paving of the drainage subgrade. As a result, a drainage subgrade layer with a 28-day compressive strength of 26.43 MPa and permeability coefficient of 18.86 mm/s was successfully applied in a highway tunnel. This study provides a theoretical framework and technical support for widespread application of pervious concrete in drainage subgrade of high-traffic load road.

COST AND TIME ANALYSIS USING THE CRASHING METHOD ON THE PROBOLINGGO – BANYUWANGI TOLL ROAD PROJECT PEKET 2: STA 9+000 – 20+200

The government is building toll roads in various regions in Indonesia to realize economic acceleration and minimize economic inequality in society. However, based on facts on the ground, there are still many delays in toll road construction projects which are detrimental so it is necessary to take steps to accelerate the work. The aim of this research is to analyze the time and costs of accelerating the Probolinggo – Banyuwangi Toll Road construction project STA 9+000 – 20+200 using the Crashing Method.

Influence of anionic polyacrylamide on the freeze–thaw resistance of silty clay

Freeze–thaw (FT) alternation can severely affect the properties of fine–grained soils, often leading to the failure of foundation backfill projects, such as open canals and roads in cold regions. To address these problems, a water–soluble anionic polyacrylamide (APAM) was used to improve the properties of fine–grained soils, particularly silty clay. This study aims to analyze the effects of the APAM polymer on the physico–mechanical and microstructural properties of silty clay under both unfrozen and FT cycles. For this purpose, different addition dosages and FT cycle numbers were determined, and then a series of zeta potential, thermal conductivity, permeability, triaxial compression, and scanning electron microscopy (SEM) tests were conducted on the soil samples. Additionally, a unidirectional freezing test was constructed to investigate the coupled thermo–hydro–mechanical processes of APAM–treated soil samples under subzero temperature conditions. The results showed that the addition of the APAM polymer significantly enhanced the macroscopic engineering properties and microstructural characteristics of silty clay. This improvement was attributed to the charge neutralization, adsorption bridging effect, and hydrophobic interaction provided by the APAM polymer. However, all the soil samples showed a significant deterioration in their engineering properties during FT cycles, especially after the third FT cycle. It was notable that APAM–treated soil samples were superior to the untreated sample in terms of FT resistance. During the unidirectional freezing process, the pore water migrated from the unfrozen zone towards the freezing front due to the temperature gradient. The treated sample's pore water migration volume was considerably lower than that of the untreated sample, resulting in a 55.25% reduction in total frost heave when the APAM dosage was 0.30%. The findings of this paper may be utilized to mitigate the risk of frost damage to foundation backfill projects in cold regions, as well as to get a better understanding of the stabilization mechanism of the eco–friendly APAM polymer.

Mechanism of physical hardening on the fracture characteristics of polymer-modified asphalt binder

This article aims to reveal the physical hardening mechanism of polymer-modified asphalt binder (PMA) and accurately assess its impact on the low-temperature fracture properties of asphalt binders. Base asphalt binder (BA), styrene–butadiene–styrene modified asphalt binder (SBSMA), and crumb rubber modified asphalt binder (CRMA) were used as the research objects. Molecular dynamics (MD) simulation and differential scanning calorimetry (DSC) test were used to investigate the physical hardening mechanism of PMA at the microscopic level. The fracture characteristics of PMA under physical hardening were analyzed based on the single-edge notched beam (SENB) test. The results show that under prolonged cold service conditions, the asphalt molecular mobility is weakened, the non-bond energy and the free volume are reduced, and the molecules undergo aggregation state transformation, leading to the physical hardening of asphalt materials. In the process of physical hardening of asphalt molecules in the micro-Brownian motion of the main active force from the aromatic and saturate fractions. Considering the effect of physical hardening, it is recommended that the method used to test the low temperature properties of asphalt binders should ensure a constant temperature for at least 24 h. The crack tolerance (Ct) is recommended as the evaluation index of low-temperature cracking resistance of PMA in cold regions. The Ct of BA, SBSMA, and CRMA are reduced by 52.88 %, 12.04 %, and 35.24 %, respectively, after 24 h of constant low temperature. This indicating that the polymer modifiers can improve the fluidity of asphalt molecules, inhibit molecular aggregation, and reduce the effect of physical hardening on asphalt binders. Thermo-oxidative aging can aggravate the physical hardening phenomenon of asphalt binder, and the higher the degree of thermo-oxidative aging, the more severe the physical hardening of asphalt binder. The related research results provide the theoretical basis and technical support for the accurate design and development of the low-temperature performance of asphalt binders for roads in cold regions.

Automatic Detection of Pedestrian Crossing Platform using Congestion Monitoring

Abstract: One of the primary problems faced globally is the amount of traffic on the roads and the number of pedestrian accidents. The risk when crossing or walking on roads in urban and rural regions with significant traffic is a major factor in these incidents. A novel idea is put forth to avert such situations. Using congestion monitoring, automatic detection of pedestrian crossing platforms. An IR (Infrared) sensor module is used to continuously monitor pedestrian and traffic congestion. When there are more pedestrians on the road, the traffic light for automobiles turns red, allowing pedestrians to cross at the zebra crossing. In the proposed system, we are counting the packed pedestrians at the signal point and performing congestion monitoring of the pedestrian and vehicle count, which will be sensed by IR Infrared Sensors. This technique guarantees pedestrian crossing safety and prevents drivers from flouting the law, which could cause accidents.

Improvement of Tiny Object Segmentation Accuracy in Aerial Images for Asphalt Pavement Pothole Detection.

In this study, we propose an algorithm to improve the accuracy of tiny object segmentation for precise pothole detection on asphalt pavements. The approach comprises a three-step process: MOED, VAPOR, and Exception Processing, designed to extract pothole edges, validate the results, and manage detected abnormalities. The proposed algorithm addresses the limitations of previous methods and offers several advantages, including wider coverage. We experimentally evaluated the performance of the proposed algorithm by filming roads in various regions of South Korea using a UAV at high altitudes of 30-70 m. The results show that our algorithm outperforms previous methods in terms of instance segmentation performance for small objects such as potholes. Our study offers a practical and efficient solution for pothole detection and contributes to road safety maintenance and monitoring.

Innovative Air Convection Embankment for Cold/Arctic Region Low-Volume Roads

Roadbed thaw settlement is a unique challenge for the durability of low-volume roads (LVRs) in permafrost regions. Air convection embankment (ACE) is an effective technique that acts as a semi-heat-transfer system to control temperature variation and reduce the thaw depth of subsoil. However, limited by the shortage of the necessary crushed rocks within a short distance, building an ACE in Alaska, U.S., is prohibitively expensive. Previous studies identified the feasibility of using cellular concrete for ACE and determined the optimized thickness of the cellular concrete aggregate interlayer for ACE. However, the economic efficiency and thermal and mechanical performance of the optimized, innovative cellular concrete aggregate ACE need further investigation. Therefore, two innovative cellular concrete ACEs with reasonable heights for cold/Arctic region LVRs were evaluated in this study. A thermal-mechanical coupling model was created using ANSYS Fluent and ANSYS Mechanical to evaluate the thermal and mechanical stability of the two optimized innovative cellular concrete aggregate ACEs by comparing them with a typical Alaskan flexible pavement, a silty sand/gravel embankment, and a conventional crushed-rock ACE. The fatigue damage was predicted using the elastic-based Alaska Flexible Pavement Design (AKFPD) program. A life-cycle cost analysis was conducted using AKFPD to evaluate the overall long-term economic efficiency of the cellular concrete ACEs. The results showed that cellular concrete ACE could achieve better thermal and mechanical performance with much lower embankment height than crushed-rock ACE. The cost analysis showed that the proposed cellular concrete ACEs had a significant cost advantage over the conventional crushed-rock ACE.

Climate change impacts the state of winter roads connecting indigenous communities: Case study of Sakha (Yakutia) Republic

Winter roads, or zimnik, serve as major connections between communities across the global Arctic, including Sakha (Yakutia) Republic. Although accessible to general public, winter roads in remote regions are primarily used by indigenous communities. Sustainability of winter roads is reduced by climate change effects, via shorter and milder winters, extended shoulder seasons, delayed freeze up and advanced ice break up on rivers used as ice roads. We review the observed and projected change in mean monthly air temperatures, MMAT, °C, during cold season in six localities of the Sakha (Yakutia) Republic, important residence areas of the indigenous peoples of the North. In observed MMAT records, only North-Western Yakutia hasn’t experienced significant warming. In other localities, a significant step-shift change is observed in months from March to June, and at several stations, also in October and November. Under future climate, assessed with a regional ensemble of global climate models, projected change is expected in core winter months, November to February. In the near future, 2021–2050 period, increase in MMAT is expected mostly in December and January, with only minor increase in shoulder seasons, except in southern Yakutia. In the far future, 2071–2100, only under optimistic SSP 1–2.6 scenario the MMAT change is contained within +3.5 °C, and even in this case, April MMAT increases above −2°C at stations in southern Yakutia. Under SSP 5–8.5 scenario, highest MMAT increase, up to over +12 °C, is projected in the Yakutian Arctic from December to February. In southern Yakutia, both October and April MMAT around or above 0 °C are projected. Winter Road Sustainability Index is assessed based on observed and projected climate. Over northern Yakutia, higher MMAT in core winter months suggest reduced ice thickness on rivers, but overall climate severity allows sustainable winter road operations throughout the season even under high emission scenarios. In the near future, only winter road operations around Tyanya, in the Evenki residence area, become moderately affected under most SSP scenarios. In the far future, winter road operations around Tyanya, Ust-Maya and Neryungri, also Evenki residence area, become highly vulnerable under most scenarios. Practical implications include institutional response, transport system adaptation, adjustment of road maintenance protocols, and reconsidering local production.

Сеть автомобильных дорог Дальнего Востока России: состояние и региональная ценовая дифференциация строительства

The paper considers the road network of the Far Eastern Federal District, which determines the possibilities of road transport, and assesses its role in the transport complex of the macroregion. The purpose of the work is to analyze the key parameters of the road network and regional features of the formation of the cost of road construction. The dynamics of the road network in the period 2015–2021 and its qualitative characteristics are considered. There is a predominance of regional roads in the northern regions of the Far East, while in the southern regions local roads predominate; as well as the lag of the macroregion in terms of the quality of the road network from the average Russian indicators. The increase in the intensity of trunk transit in 2022 against the backdrop of the reorientation of the main part of export cargo to the Pacific regional direction led to the tendency to transfer part of the intraregional cargo from rail to road transport. This actualizes the need for the development of roads and the assessment of the rise in the cost of road construction, taking into account the conditions of the Far Eastern regions of the Russian Federation. To analyze the differences in the conditions of road construction between the territories of the Far Eastern Federal District, 38 price zones were identified. Using the basic-index method for each price zone, the coefficients of appreciation of costs for the construction a conditional road facility were calculated (standard works for the construction of 1 km of a category II highway was taken into account). As a result, the interval of the coefficient of appreciation of costs for the construction and installation works (relative to the base facility) in the Far East ranged from 1,02 (Republic of Buryatia; price zone V) to 1,93 (Chukotka Autonomous Okrug; price zone II). The obtained estimates of cost differentiation for the selected price zones of the Far Eastern Federal District are presented on the cartogram

Analisis Kehilangan Gaya Prategang Girder Pada Jembatan Proyek Pembangunan Jalan Tol Tebing Tinggi – Inderapura

Currently, the construction of toll roads in several regions of Indonesia is being carried out. One of them is the construction of the Tebing Tinggi-Inderapura Toll Road. In this project there are several bridge constructions as a link between roads or as a pedestrian bridge. This bridge uses prestressed beams in which there are steel wires. The steel wire is tensioned by pulling it using a hydraulic jack. When stress is applied, the beam loses its prestressing force. The purpose of this study was to determine the percentage loss of prestressing forces that occurred in the bridge beam. Loss of prestressing force must not exceed the maximum that has been determined. There is some loss of prestressing force which is taken into account. Short-term prestress losses include elastic shortening of the concrete, friction along the tendons and anchor slippage. Furthermore, the loss of long-term prestressing forces is creep in steel, shrinkage in concrete and relaxation of steel. After all the loss of prestressing force is calculated, the total loss of prestressing force is 21.62%. To find out the maximum percentage of loss of prestressing force using calculations from the book Design of Prestressed Concrete Structures by T. Y. Lin H. Burns with the formula Pe/Ac and the value is 8.98 MPa. Where 8.98 MPa is 25%, so 21.62% is smaller than 25%, so it is still safe. In addition, an implementation method for installing girders on bridges is introduced..

The impact of natural factors on the condition of roads in various regions of Russia

The article is devoted to the peculiarities of taking into account natural and climatic conditions when designing a highway. It is shown that environmental conditions directly affect the specifics of the designed roads. However, they can play a dual role: both to promote and counteract the long service life of the roadbed. Since it is impossible to influence the weather conditions, it is necessary to provide full protection of the highway. All factors affecting the road condition at the early stages of design were analyzed. It is concluded that if the regulatory and technical requirements are not met, the quality and safety of the road will not be ensured for each road and climate area.in this regard, the most effective methods of protecting and reducing the negative effects of environmental impact were considered.

Multiphysics based Analysis of Materials for Roads in Cold Regions to Prevent Ice Adhesion and Low-Temperature Crack Developments

Roads constitute a significant hazard if the effects of wintertime are not handled well. After a heavy snowfall, the most dangerous factor is a slippery surface due to ice adhesion with the asphalt pavement. The ice on roads increases the risk of road accidents and, upon melting, contributes to the formation of Low-Temperature Cracks (LTCs) and potholes. This research explores the physical principle that could remove the ice from concrete roads by investigating whether road ice is susceptible to self-separation upon loading when the road surfaces in cold regions are coated with a polymer-based material such as polyurethane. This study conducted an experimental and numerical analysis of ice-polyurethane and ice-concrete separation under tensile load and calculated the Von-Mises stresses on the surfaces. Results revealed higher Von-Mises stresses on ice when the base material is polyurethane compared to concrete, indicating ice is more prone to self-separation when adhered to polyurethane than concrete. These results are important for increasing the operational life of roads in cold regions and reducing the number of road accidents. In addition, polyurethane is a potential material for pre-emptive road measures, such as repairing cracks before they become potholes.

Toll Road Development and Environmental Change: A Maqashidi Study at Indralaya – Muara Enim

The Government of Indonesia builds toll roads in many regions of Indonesia, including 119 km of the Indralaya - Muara Enim intersection, to accelerate barrier-free connectivity for the community. This study analyzes the concept of environmental change from the impact of the construction of the toll road on the Indralaya community. This study uses a qualitative approach with an inductive research type. The data were analyzed using NVivo 12 Plus. The results showed that environmental change must be based on the principle of mutual benefit. The construction of toll roads must involve the local community to create conducive conditions. Negative impacts on the environment in the development process must be minimized through dialogue and contributions from the surrounding community. The construction of the Indarala – Muara Enim toll road in general has met the requirements of ushul al khamsah or basic needs of maqashid sharia. However, there is still a lack of anticipation from this implementation project because there are still complaints from the public, which can be read from respondents' responses. Environmental changes related to the construction of toll roads must use a structured and orderly concept. In this case, the concept of environmental change must be bound by the rules and legislation to anticipate and provide solutions to the negative impacts that occur in the form of minimal compensation for land or buildings affected by the project at a reasonable price, dealing with contaminated or polluted air and noise quickly and responsively.

Regulating the albedo and radiation absorption of engineering surfaces for cooling the embankments in high-altitude permafrost regions

Under the influences of global warming and strong solar radiation, the construction of the wide high-grade roads in high-altitude permafrost regions becomes more challenging. To reach the challenges and further improve the thermal-mechanical stabilities of the permafrost embankment, this study proposes a novel cooling embankment structure based on the heat-reflective coatings. The principle is to reduce and regulate the solar radiation absorption by the permafrost embankment surface, thus improving the temperature field of the embankment and preventing uneven settlement and other freeze-thaw damages of the embankment. First, a theoretical-empirical model is proposed to describe the transfer processes of incident radiations on the pavement and slope surfaces. Based on the model, we carry out a systematic study of the main factors influencing the solar radiation absorption of the embankment surfaces and their variation patterns. By analyzing the calculation results, we propose the regulating schemes of the heat-reflective coatings for the radiation absorption balance of the embankment surfaces. Meanwhile, the solar albedo properties of the heat-reflective coatings under different solar spectral are also studied. The results indicate that the heat-reflective coatings can significantly reduce the solar radiation absorbed by the embankment surfaces. It proves that the cooling embankment structure and albedo regulation schemes proposed in this paper are expected to be applied in practical engineering. Finally, we discuss the shortcomings of the current research and the next research plans.
