Description

Technical Field

[0001] This invention relates to the field of dynamic monitoring and slope protection and reinforcement technology, specifically to a method and system for road cut slope protection and reinforcement based on dynamic monitoring technology. Background Technology

[0002] Cut slopes are formed by excavation on sloping terrain and are a common type of slope in transportation facilities such as highways and railways. The geological conditions of cut slopes are complex, including different layers of soil and rock, varying degrees of weathering, and the development of fissures. These factors significantly impact the stability of the slope during excavation, support, and reinforcement. Landslides and collapses can pose a serious threat to the safety of people and property.

[0003] Existing methods for monitoring and reinforcing road cut slopes are unable to provide real-time monitoring and rapid data transmission. Furthermore, existing monitoring methods often rely on single detection technologies or monitoring methods, lacking the comprehensive application and technological complementarity of multiple monitoring methods. This results in biased and uncertain monitoring results for road cut slopes, failing to fully reflect the actual condition and stability of the slopes.

[0004] The effectiveness and sustainability of slope protection and reinforcement projects require long-term monitoring and evaluation. However, existing slope analysis methods lack long-term monitoring plans and evaluation mechanisms, making it difficult to promptly identify and address problems in slope reinforcement projects. Therefore, to solve these problems, it is necessary to improve and optimize existing slope monitoring and protection / reinforcement methods, enhance slope stability and safety, and promote the development and advancement of related technologies.

[0024] Please see Figure 1 This invention utilizes dynamic monitoring technology to track and monitor key parameters of road cut slopes in real time. Based on this, a multi-dimensional analysis system is constructed. This system can analyze multiple key reference factors of road cut slopes from all angles and perspectives, providing information support for the formulation of road cut slope protection and reinforcement schemes. It also provides slope managers with a solid and reliable analytical basis, further ensuring the scientific validity and effectiveness of road cut slope protection and reinforcement schemes. This invention provides a road cut slope protection and reinforcement method based on dynamic monitoring technology, which includes the following steps: S1. Establish a real-time monitoring network for road cut slopes based on dynamic monitoring technology, and obtain dynamic monitoring information of road cut slopes through the real-time monitoring network. The specific implementation steps and contents are as follows. I. The planning and design phase of the monitoring network.

[0025] During the planning and design phase of the monitoring network, the primary task is to clarify the monitoring objectives, which requires determining the specific monitoring locations, monitoring ranges, and importance levels of the road cut slopes. In this embodiment, the monitoring content includes, but is not limited to, key evaluation parameters such as slope displacement, deformation and cracking, groundwater level, rainfall, dimensional measurements, and physical properties.

[0026] Next, considering the topographical features and geological conditions of the road cut slope, as well as the established monitoring requirements, the layout of monitoring points is planned to ensure that each point effectively reflects the actual situation of the road cut slope. Simultaneously, appropriate monitoring equipment and technologies are configured, such as GPS displacement monitors, inclinometers, water level gauges, and rain gauges. Furthermore, the method of transmitting monitoring information must be determined; whether wireless, wired, or satellite communication is used, the stability and real-time performance of the information transmission must be ensured.

[0027] Building upon this foundation, the overall architecture of the real-time monitoring network for road cut slopes will be further improved. This architecture includes data acquisition, data transmission, data processing and analysis, and user interaction. Simultaneously, the hardware and software configuration requirements for the monitoring network, as well as detailed data storage and backup plans, will be clearly defined to ensure the integrity and security of the monitoring information.

[0028] II. Implementation and Deployment Phase of the Monitoring Network.

[0029] First, according to the design plan, different types of monitoring equipment are installed at the preset monitoring points, and the equipment is debugged and calibrated. This helps to ensure that all equipment is in the best working condition, thereby ensuring the stability and reliability of data transmission.

[0030] Next, a data transmission network is established. The real-time monitoring network for road cut slopes can include various forms such as wireless networks, wired networks, or satellite communication networks to meet the data transmission needs in different scenarios. After the network is established, a comprehensive test is conducted to ensure the real-time performance and accuracy of data transmission, laying a solid foundation for road cut slope protection and reinforcement methods.

[0031] Finally, the monitoring equipment, data transmission network, and data processing and analysis system are deeply integrated. This process facilitates the collaborative work between various devices, thereby ensuring that the entire monitoring network can efficiently and accurately complete data acquisition, transmission, and processing tasks. After integration, a comprehensive system debugging will be conducted to further verify the stability and reliability of the real-time monitoring network for road cut slopes.

[0032] III. Operation and Maintenance Phase The real-time monitoring network for road cut slopes is activated to collect and transmit dynamic monitoring information of the road cut slopes in real time. The road cut slope protection and reinforcement system can display the monitoring data in real time, perform preliminary analysis of the detection information, and issue early warning or alarm information based on the preliminary analysis results, such as displacement exceeding the threshold or abnormal groundwater level.

[0033] The real-time monitoring network for road cut slopes can employ various analysis methods, such as time series analysis, statistical analysis, and data mining, to process and analyze the collected dynamic monitoring information. Based on the analysis results, it can also generate preliminary monitoring reports and initial assessment reports. These reports mainly include statistical information on the monitoring data, comparison results of slope physical properties, and relevant protection and reinforcement recommendations.

[0034] On the other hand, in order to ensure the feasibility and accuracy of dynamic monitoring information on road cut slopes, it is necessary to maintain and optimize the real-time monitoring network for road cut slopes, regularly maintain and service the monitoring equipment to ensure its normal operation, and optimize and upgrade the monitoring equipment in a timely manner to help improve the stability and reliability of the monitoring network. In addition, it is necessary to adjust the monitoring points and monitoring parameters according to actual needs and monitoring results. Based on this, an efficient and reliable real-time monitoring network for road cut slopes has been established, providing comprehensive and accurate information support for slope stability assessment and the formulation of protection and reinforcement schemes.

[0035] Furthermore, the method for obtaining dynamic monitoring information of road cut slopes in this embodiment is merely an optional condition of the present invention. In other embodiments, the method for obtaining dynamic monitoring information of slopes can be flexibly adjusted according to the protection and reinforcement requirements of the road cut slopes and the structure of the monitoring network. Based on the actual condition of the slopes and the specific requirements for protection and reinforcement, the most suitable monitoring equipment and data processing methods can be selected to ensure the accuracy and reliability of the obtained dynamic monitoring information and provide solid information support for the protection and reinforcement work of road cut slopes.

[0036] S2. Based on the dynamic monitoring information and the needs for slope protection and reinforcement in step S1, a multi-dimensional analysis system for road cut slopes is constructed. The specific implementation steps and contents are as follows: Based on the aforementioned dynamic monitoring information and the requirements for slope protection and reinforcement of road cuts, a first, second, and third index layer for road cuts was established. Furthermore, based on these first, second, and third index layers, a multi-dimensional analysis system for road cuts was derived, the details of which are as follows: In this embodiment, a first index layer for the cut slope is set based on dynamic monitoring information. The first index layer mainly includes the sliding resistance, slope sliding force, erosion resistance and seepage pressure of the cut slope, which helps to systematically analyze the stability and safety of the cut slope in the subsequent process.

[0037] The sliding resistance of road cut slopes can be used to measure the ability of slope soil to resist sliding. The magnitude of the sliding resistance is closely related to factors such as the physical and mechanical properties of the slope soil, the geometry of the slope, and groundwater conditions. Dynamic monitoring information can be used to monitor the changes in slope sliding resistance in real time, thereby enabling timely assessment of slope stability.

[0038] Slope sliding force is the main force that drives slope soil to slide. Its magnitude depends mainly on factors such as the weight of the slope soil, the slope inclination angle, and the lubricating effect of groundwater on the soil. Accurately calculating the slope sliding force based on dynamic monitoring information can help determine whether there is a risk of slope sliding.

[0039] For road cut slopes located in areas with strong water erosion, such as rivers and streams, their erosion resistance can reflect the ability of the slope soil to remain stable under the action of water erosion. A dynamic monitoring network can be used to understand the erosion resistance of the slope, which helps to design corresponding protection measures and prevent the slope from becoming unstable due to erosion.

[0040] Seepage pressure refers to the pressure generated by groundwater in the slope soil. When the seepage pressure is too high, it may reduce the effective stress of the slope soil, thereby increasing the risk of slope sliding. Therefore, dynamic monitoring of seepage pressure is of great significance for assessing the stability of slopes.

[0041] In this embodiment, sliding resistance, slope sliding force, erosion resistance, and seepage pressure are set as the first indicator layer of the multidimensional analysis system for road cut slopes. This helps to fully understand the stability and safety status of road cut slopes and provides strong data support and decision-making basis for subsequent slope protection and reinforcement work.

[0042] A second index layer for the road cut slope is set based on dynamic monitoring information. The second index layer includes the average height of the road cut slope, the degree of crack development, the slope cross-sectional characteristics, the water content, the internal friction force, and the cohesion coefficient.

[0043] To further refine the multi-dimensional analysis system for road cut slopes, a second indicator layer was set up in this embodiment based on dynamic monitoring information. This indicator layer aims to conduct an in-depth analysis of the stability and safety status of the slope from a more specific perspective. The second indicator layer in this embodiment mainly includes the following key indicators: The average height of a road cut slope is one of the important factors affecting its stability. Higher slopes often face greater gravitational forces, thus increasing the risk of landslides. Dynamically monitoring the average height of a slope can assess its potential sliding energy and provide a basis for slope protection and reinforcement design.

[0044] Slope fissures are weak points in slope soil, acting as concentrating channels for water flow and stress, which accelerates the slope failure process. The embodiment dynamically monitors the development of fissures, including their number, length, width, and distribution, helping to promptly identify and address potential slope slip surfaces.

[0045] Slope cross-sectional characteristics, including but not limited to the cross-sectional shape, inclination angle, and surface roughness, have a significant impact on its stability. By dynamically monitoring relevant characteristic information, the geometry of the slope can be understood, thereby assessing its ability to resist sliding and scouring.

[0046] The water content ratio of a road cut slope is an important indicator reflecting the moisture content of the slope soil. An excessively high water content ratio will reduce the strength and stability of the soil and increase the risk of landslides. Combining weather forecasts and groundwater level monitoring information can help road cut slope protection and reinforcement methods accurately predict the potential landslide risk of the slope and take corresponding preventive measures.

[0047] Internal friction is the force between particles within the soil, which determines the shear strength of the cut slope soil. By dynamically monitoring internal friction, we can understand the mechanical properties of the slope soil and assess its ability to resist sliding.

[0048] Cohesion is the mutual attraction between soil particles due to physical and chemical interactions. The cohesion coefficient reflects the strength of this attraction. Combined with other mechanical parameters, it can more accurately assess the stability of a slope.

[0049] In summary, by setting average height, crack development degree, slope cross-sectional characteristics, water content, internal friction force, and cohesion coefficient as specific reference factors for the second index layer, the stability and safety of cut slopes can be comprehensively assessed from multiple perspectives. This will provide more refined and accurate data support for slope protection and reinforcement work, and help ensure the safety and stability of different cut slopes.

[0050] The third index layer of the road cut slope is set based on dynamic monitoring information. In this embodiment, the third index layer mainly includes engineering geological information, meteorological and hydrological characteristics, support engineering and greening, rainfall and drainage facilities. In the process of constructing the road cut slope stability assessment system, the embodiment sets up a third index layer based on dynamic monitoring information. The third index layer mainly focuses on the external environment and human intervention factors that affect slope stability, aiming to comprehensively consider factors such as the engineering geological background, meteorological and hydrological conditions, support and greening projects, rainfall and drainage facilities of the slope.

[0051] Engineering geological information includes information such as the soil and rock type, stratigraphic structure, geological structure, fault and joint development of the area where the slope is located. These factors have a significant impact on the stability of the slope. By dynamically monitoring changes in engineering geological information, we can understand the geological background of the slope in a timely manner and provide a scientific basis for the design of slope protection and reinforcement.

[0052] Meteorological and hydrological characteristics, such as meteorological conditions like temperature, humidity, and wind speed, and hydrological conditions like river flow, groundwater level, and groundwater dynamics, are important factors affecting slope stability. Dynamic monitoring of these characteristics helps predict extreme weather and hydrological events that slopes may face, allowing for timely preventative measures and reducing the risk of slope instability.

[0053] Support engineering and greening include support engineering such as retaining walls, anti-slide piles, and anchor bolts, and greening measures such as vegetation slope protection, grass planting, and tree planting. These are important means to enhance slope stability. By dynamically monitoring the stability of support engineering and the effect of greening, the effectiveness of engineering measures can be evaluated, which is conducive to timely adjustment and optimization of support and greening plans to ensure the long-term stability of the slope.

[0054] Rainfall is one of the key factors affecting slope stability. Continuous heavy rainfall in the area where the road cut slope is located may saturate the slope soil, reduce its shear strength, and increase the risk of sliding. Dynamic monitoring of rainfall can provide timely warning of potential landslide risks and take corresponding emergency measures.

[0055] Drainage facilities are an important component of slope protection engineering. They can effectively remove accumulated water from slopes, reduce the adverse effects of groundwater on slope stability, and dynamically monitor the operation status and drainage effect of drainage facilities to ensure unobstructed drainage, improve the drainage capacity of slopes, and thus reduce the risk of landslides.

[0056] The embodiment sets up a third indicator layer including engineering geological information, meteorological and hydrological characteristics, support engineering and greening, rainfall and drainage facilities. This helps to comprehensively consider the external environmental factors and human intervention factors affecting the stability of road cut slopes, and provides more comprehensive and accurate data support for the monitoring, evaluation and protection and reinforcement of different road cut slopes, which helps to ensure the effective implementation of road cut slope protection and reinforcement methods.

[0057] Furthermore, the method for constructing the multidimensional analysis system for road cut slopes in this embodiment is merely an optional condition of the present invention. In other embodiments, the method for establishing the multidimensional analysis system for road cut slopes can be changed according to the specific conditions of the road cut slopes and the actual needs of protection and reinforcement. Different road cut slopes have different geological, topographical, and climatic conditions. By changing the method for constructing the analysis system, these differences can be considered more specifically, thereby formulating monitoring and protection schemes that are more in line with the actual situation.

[0058] S3. Based on the above multi-dimensional analysis system and dynamic monitoring information of the cut slope, the analysis results of the first, second, and third indicators of the cut slope are obtained. The specific implementation steps and contents are as follows: In an optional embodiment, a sliding resistance analysis model, a sliding force analysis model, a slope erosion analysis model, and a slope seepage pressure analysis model are established based on the first index layer and dynamic monitoring information. At the same time, the first index analysis results of the road cut slope are obtained by using the above-mentioned sliding resistance analysis model, sliding force analysis model, slope erosion analysis model, and slope seepage pressure analysis model.

[0059] First, based on the first index layer and dynamic monitoring information, we establish a sliding resistance analysis model for slope sliding, a sliding force analysis model for slope sliding when resistance changes, a slope erosion analysis model, and a slope seepage pressure analysis model.

[0060] To delve into the mechanical changes of cut slopes under critical sliding conditions and their impact on velocity, and to establish a more realistic model standard within the multidimensional analysis system of cut slopes, the embodiments specifically consider water as a crucial factor. Therefore, a novel high-slope rock sliding model was constructed, namely the sliding resistance analysis model for slope sliding in the embodiments, aiming to accurately assess the sliding situation of cut slopes under natural conditions. A schematic diagram of the cut slope can be found in the attached diagram. Figure 2 ,in This indicates the angle of the cut slope, that is, the angle of inclination of the slope base relative to the horizontal plane. h Indicates the height of the road cut slope. This indicates the total length of the cut slope surface.

[0061] The above-mentioned sliding resistance analysis model for slope sliding satisfies the following relationship:

[0062] in, This represents the sliding resistance when the roadbed slope slides down. Indicates the quality of the road cut slope. Represents gravitational acceleration. Indicates the angle of the cut slope. This indicates the surface seepage pressure of the road cut slope. This represents the cohesion coefficient of the cut slope. Indicates the total length of the cut slope surface; The sliding resistance of a road cut slope refers to the force that prevents the slope's soil and rock mass from moving downwards and outwards along a certain sliding surface. During the slope sliding process, the magnitude and distribution of the sliding resistance directly affect the stability of the slope.

[0063] Surface seepage pressure on a road cut slope refers to the pressure generated by groundwater or rainfall seeping into or within the slope surface. This pressure significantly impacts slope stability. When groundwater flows through soil or fractured rock, it encounters resistance from soil particles or rock fragments. To overcome this resistance, the water exerts a force on the soil particles or rock fragments, creating dynamic water pressure or seepage force. This dynamic water pressure accumulates on or within the slope surface, forming the surface seepage pressure described in this example.

[0064] The cohesion coefficient of a road cut slope describes the magnitude of cohesive forces, such as cementation between soil particles or intermolecular attraction, and is one of the key factors affecting slope stability. Cohesion is mainly formed by the cementation between soil particles or intermolecular attraction, and is related to factors such as soil structure, mineral composition, content, and moisture content. In slope stability analysis, the cohesion coefficient can be considered as an important parameter for shear strength. When the cohesion coefficient is large, the shear strength of the slope soil will also increase accordingly, thereby increasing the stability of the slope.

[0065] The total length of a road cut slope surface refers to the straight-line distance measured along the slope surface from the top to the bottom or a specific horizontal plane. This length is one of the important parameters describing the slope's shape and dimensions, and is of great significance for slope stability analysis, design, and construction. In road cut engineering, the total length of the slope surface can be used to calculate the slope gradient, determine the scope of slope stability analysis, and design reinforcement measures. By measuring the total length of the slope surface, the slope's inclination and shape characteristics can be understood, thereby assessing its potential sliding risk and stability.

[0066] Based on the above-mentioned sliding resistance analysis model for slope slippage, the vulnerable area formed by slope movement can be further named the landslide zone. When the landslide zone fully absorbs water and fills the void between the landslide body and the base rock layer, the sliding resistance will decrease accordingly. At this time, due to the effect of the landslide zone's own gravity, it will have a downward movement tendency. In the embodiment, the sliding force generated when the resistance decreases is analyzed. The above-mentioned sliding force analysis model for slope when the resistance changes satisfies the following relationship:

[0067] in, This represents the sliding force of the cut slope when the resistance decreases. Indicates the quality of the road cut slope. Represents gravitational acceleration. Indicates the angle of the road cut slope; The sliding force of a road cut slope when resistance decreases refers to the force generated when the resistance on the slope sliding surface decreases due to various reasons, such as rising groundwater levels leading to surface wetting or reduced soil strength. This sliding force is the direct cause of slope instability and landslides. In slope stability analysis, the magnitude of the sliding force mainly depends on the weight of the road cut slope soil and the inclination angle of the sliding surface. When the resistance decreases, the sliding force will relatively increase, thereby increasing the risk of slope instability.

[0068] When faced with rainwater erosion, the erosion resistance of cut slopes is a key factor in ensuring slope stability and vegetation growth. Rainwater erosion leads to gully erosion, erosion cracks, and delamination of the substrate from the slope surface. These forms of damage weaken or destroy the substrate for plant growth, thereby hindering the formation and development of slope biological communities. In this embodiment, the slope erosion index is used to assess the slope's erosion resistance. This index quantifies the stability of the slope surface under rainwater erosion and helps to quantify and understand the impact of factors such as slope materials, vegetation cover, and slope protection techniques on erosion resistance.

[0069] The erosion resistance of road cut slopes is closely related to factors such as the material properties, vegetation cover, and effectiveness of slope protection measures. High-quality road cut slope materials should have good permeability and erosion resistance, effectively resisting the erosion effect of rainwater. Vegetation cover can increase the roughness of the slope surface and slow down the water flow velocity, thereby reducing the erosion effect. Effective slope protection measures can further enhance the erosion resistance of the slope surface.

[0070] Therefore, when designing and implementing slope protection projects, I need to fully consider the slope's erosion resistance and select appropriate slope materials, vegetation types, and protection techniques to ensure slope stability and vegetation growth. At the same time, we also need to strengthen monitoring and maintenance to promptly identify and address potential erosion problems, ensuring the long-term safety and stability of the slope.

[0071] The above slope erosion analysis model satisfies the following relationship:

[0072] in, This indicates the scour index of the cut slope surface. This indicates the area of ​​gullies in the cut slope. This represents a constant value corresponding to the length of cracks in the cut slope. This indicates the length of cracks on the surface of the road cut slope. This indicates the area where the substrate has peeled off from the surface of the road cut slope. This indicates the surface area of ​​the road cut slope; The scour index of the cut slope surface can be used as a quantitative indicator to evaluate the slope's resistance to scour. It can reflect the comprehensive influence of factors such as slope surface materials, vegetation cover, and slope protection measures on the resistance to scour.

[0073] In this embodiment, the gully area in a road cut slope refers to the area occupied by gullies formed on the slope surface due to rainwater erosion and other effects. This gully area weakens slope stability to some extent, affecting slope safety, and also negatively impacts vegetation growth and the landscape. During slope engineering design and construction, the impact of the gully area must be fully considered. Reasonable slope design, selection of materials with good erosion resistance, and implementation of effective drainage and protection measures are necessary to reduce the generation and development of gullies, thereby ensuring the safety and stability of different road cut slopes.

[0074] The constant value corresponding to the crack length in a road cut slope refers to the standard or threshold used in road cut slope engineering to describe and classify crack length. Specifically, crack length can be divided into different categories according to its size, such as micro-cracks, fine cracks, medium cracks, and large cracks. The classification of these categories is usually based on the specific numerical range of crack length, which helps to subsequently assess the severity of slope cracks and develop corresponding maintenance and reinforcement plans.

[0075] The crack length on the surface of a road cut slope refers to the horizontal or near-horizontal extension distance of cracks on the slope surface caused by natural factors such as weathering, rainwater erosion, or human factors. In this embodiment, the crack length can be measured using professional measuring tools, such as crack width gauges or tape measures, to directly measure the distance from the start to the end of the crack. Simultaneously, the accuracy and precision of the measuring tools must be ensured during measurement to avoid errors.

[0076] The area of ​​delamination between the substrate and the cut slope surface refers to the area where the substrate used to cover or reinforce the slope surface separates or detaches from the actual slope surface during cut slope protection or greening projects. This delamination can be caused by various factors, such as insufficient adhesion between the substrate and the slope surface, rainwater erosion, and slope deformation. It is of great significance for subsequent evaluation of the stability and durability of slope protection or greening projects.

[0077] The slope area of ​​a road cut slope refers to the projected area of ​​the slope onto a plane perpendicular to its direction. It is a crucial parameter for assessing slope size and stability, as well as for slope design and protection. In practical engineering, calculating the slope area of ​​a road cut slope requires considering factors such as the slope's shape, gradient, and height. When designing and protecting slopes, the impact of the slope area must be fully taken into account, and appropriate measures must be implemented to ensure the stability and safety of the slope.

[0078] To assess the stability of different road cut slopes under rainfall conditions, geometric parameters such as slope height and length were obtained based on dynamic monitoring information of the road cut slopes. The above slope seepage pressure analysis model satisfies the following relationship:

[0079] in, This indicates the surface seepage pressure of the road cut slope. This indicates the total water-filled height of the cracks in the road cut slope. This indicates the total length of the cut slope surface.

[0080] Then, the first index analysis results of the road cut slope are obtained by simultaneously using the above-mentioned sliding resistance analysis model when the slope slides down, the sliding force analysis model when the resistance changes, the slope erosion analysis model, and the slope seepage pressure analysis model.

[0081] In an optional embodiment, a sliding resistance analysis model for slope sliding is used to calculate the resistance experienced by the cut slope during the sliding process. Simultaneously, combined with... Figure 2 As can be seen from the schematic diagram, the road cut slope is connected to the underlying bedrock by a potential sliding zone. This sliding zone is not only a connecting bridge between the landslide body and the bedrock, but also plays an important mechanical role.

[0082] To gain a deeper understanding of the sliding dynamics of a slope during a slide, the embodiment further subdivides it into three parts and calculates each part using a sliding resistance analysis model. Based on this, it can be found that the middle part of the slope plays a crucial role in resisting sliding, and the sliding resistance it provides is relatively large.

[0083] Furthermore, the segmented analysis method allows for a more detailed exploration of the mechanical properties of the slope during the sliding process, as well as the extent to which moisture affects these mechanical properties. This provides a more in-depth perspective for subsequent slope stability research and offers a strong scientific basis for formulating slope protection and reinforcement measures.

[0084] In an optional embodiment, sliding force analysis data of the cut slope when resistance decreases is obtained through a sliding force analysis model of the slope under varying resistance. Based on this, the sliding risk of the slope under adverse conditions can be quantified. Specifically, in this embodiment, the slope is considered as a complex mechanical system containing various material and structural properties, which together affect the stability of the slope. Then, the sliding force analysis model is used to simulate the distribution and changes of internal stress in the cut slope under different resistance levels.

[0085] According to the model analysis results, when the resistance on the slope sliding surface decreases, the sliding force will increase accordingly, which increases the possibility of slope sliding. The model also reveals the specific distribution characteristics of the sliding force, including the slope is most likely to become the starting point of sliding, as well as the stress transmission and change path during the sliding process. This allows for a more comprehensive assessment of the sliding risk of the slope under different conditions and provides a scientific basis for formulating effective slope protection and reinforcement measures.

[0086] In an optional embodiment, the scour index of the cut slope surface is calculated based on the slope scour analysis model. Based on this, the scour of the slope surface under different rainfall conditions can be simulated, and the corresponding scour index can be calculated. The index can reflect the ease with which the soil on the slope surface is scoured and the amount of scour.

[0087] The scour index directly reflects the scour risk of a slope under rainfall conditions. A higher scour index means that the surface soil of the slope is more easily eroded, thus requiring more effective protective measures to reduce the scour risk. Furthermore, the scour index can serve as an important reference indicator for slope stability assessment. During slope design and maintenance, corresponding reinforcement and protection measures can be formulated based on the scour index to ensure the safety and stability of the slope.

[0088] In an optional embodiment, the surface seepage pressure of the road cut slope is analyzed based on the slope seepage pressure analysis model. The analysis results provide an understanding of the water distribution and flow within the slope, which is beneficial for subsequent assessment of the slope's stability under seepage and serves as an important basis for designing protective measures and establishing an early warning system.

[0089] In this embodiment, the output results of the slope seepage pressure analysis model were used to plot the curves of seepage pressure changing over time at three key monitoring points on the cut slope. Please refer to [link / reference needed] for details. Figure 3 The three key monitoring points are numbered 1, 2, and 3 respectively.

[0090] In another alternative embodiment, the relationship between specific physical properties of the cut slope and slope cracks is analyzed based on dynamic monitoring information and the second index layer; and the second index analysis results are obtained by combining the second index layer and the relationship.

[0091] In this embodiment, based on the above-mentioned sliding resistance analysis model, sliding force analysis model of the slope when the cutting slope slides down, and slope seepage pressure analysis model, the trend of the average height change when the cutting slope slides down is further analyzed.

[0092] Based on the above-mentioned models, in the stability assessment of road cut slopes, sliding force is considered. With resistance The balance between them is crucial. When sliding force Greater than resistance When the sliding force is at its maximum, the slope will lose its balance and slide, leading to slope instability and failure. Conversely, when the sliding force... Equal to resistance At that time, the slope was in a stable equilibrium state.

[0093] Furthermore, the embodiment sets a critical state, namely when the sliding force Exactly equal to resistance At this point, the slope is in a limit state where it is about to slide but has not yet slided. In this state, the angle between the slope rock masses is... It can be called the ultimate failure angle. The ultimate failure angle is an important parameter for evaluating slope stability, which reflects the geometric and mechanical characteristics of the slope under critical conditions.

[0094] Therefore, in the stability analysis of road cut slopes, the balance between sliding force and resistance determines the stability state of the slope. When the sliding force is greater than the resistance, the slope will fail; when the sliding force equals the resistance, the slope is in equilibrium; in the critical state, that is, when the sliding force is exactly equal to the resistance, the angle between the rock masses of the slope reaches the ultimate failure angle, which is also a key parameter for evaluating slope stability.

[0095] Based on dynamic monitoring information and existing theoretical knowledge, the quality of the roadbed slope in this embodiment needs to satisfy the following relationship:

[0096] in, Indicates the quality of the road cut slope. Indicates the unit weight of the road cut slope. This indicates the average height of the rock landslide mass. This indicates the total length of the cut slope surface.

[0097] Combined with the sliding resistance analysis model during slope sliding: ; Slope sliding force analysis model when resistance changes: ; Furthermore, it can be seen that:

[0098]

[0099] This allows us to obtain the average height of the cut slope, which satisfies the following relationship:

[0100] in, This indicates the average height of the cut slope. This indicates the total water-filled height of the cracks in the road cut slope. Indicates the unit weight of the road cut slope. This represents the cohesion coefficient of the cut slope. This represents the total length of the cut slope surface. Indicates the angle of the road cut slope; The cohesion coefficient of the above-mentioned road cut slopes satisfies the following relationship:

[0101] in, This represents the cohesion coefficient of the cut slope. This represents the internal friction weighting coefficient of the road cut slope. This indicates the internal friction angle of the cut slope. This indicates the shear strength of the road cut slope.

[0102] In another alternative embodiment, the third indicator analysis results are obtained based on dynamic monitoring information and the third indicator layer.

[0103] The average height of the road cut slope at different times is obtained based on the calculation model of the average height of the road cut slope. Data from different times is input into the model for calculation. The model will calculate the corresponding average height based on the input parameters and data. Based on this, the morphological changes and future trends of the slope at different times can be analyzed.

[0104] The cohesion coefficient of road cut slopes can be calculated based on the cohesion coefficient model. This allows for the calculation and analysis of the cohesion coefficient of slopes under different geological conditions and rainfall conditions. This helps to understand the influencing factors and variation patterns of slope stability, and provides strong support for scientific research and technological advancements in slope stability.

[0105] Considering the impact of water bodies on slope stability, multiple parameter calculation functions were constructed in the second index to better reflect the actual situation of road cut slopes, further revealing the intrinsic relationship between the height, length, and slope angle of the road cut slope. To verify the practicality of the above calculation functions, a large amount of calculation work was carried out in the embodiments, and the calculation results were compared with field observation data. Please refer to Table 1 for details, which summarizes the key information of the road cut slope.

[0106] Table 1. Statistical Information on Some Parameters of Different Cut Slopes Location number slope lithology Rock mass structure average height Cohesion Moisture content Extreme Destruction Angle 1 granite thick layer 35 4.01 0.11 42 2 slate integral block 30 3.23 0.19 34 3 schist thin layer 24 2.56 0.23 35 4 Phyllite Layered 26 3.28 0.24 36 Based on the information in Table 1, the calculation model and its derivation formula established in the second index layer of the multidimensional analysis system for road cut slopes provide a powerful tool for the stability assessment of different road cut slopes, taking into account the influence of water bodies. It not only has theoretical guiding significance, but also demonstrates its reliability and accuracy in practical applications through field verification, so as to better guide the design, construction and monitoring of different road cut slope projects.

[0107] Furthermore, based on information such as the average height, fissure development degree, slope cross-sectional characteristics, water content, internal friction force, and cohesion coefficient of the cut slope in the second index layer, the specific physical characteristics of the cut slope are further analyzed, as follows: This analysis examines the relationship between the height (depth) of a road cut slope and its physical properties, such as density, dry density, and the proportion of voids in the slope. For a clearer explanation of these relationships, please refer to [link to relevant documentation]. Figure 4 .

[0108] First, the height (depth) of the cut slope is a key variable that affects the overall structure and physical properties of the slope. As the slope height (depth) increases, the gravity, stress, and possible external factors that the slope bears will also change, resulting in corresponding adjustments to the slope's physical properties such as density, dry density, and porosity.

[0109] Density refers to the mass of a substance per unit volume. For road cut slopes, as the height increases, the material inside the slope may accumulate more densely due to gravity, leading to an increase in overall density. However, on the other hand, if the slope height is too high, it may lead to decreased slope stability and geological disasters such as landslides. In this case, the density of the slope may decrease due to material loss. Therefore, the change in density depends on the combined positive and negative effects of increasing slope height.

[0110] Dry density refers to the density of a material in a dry state. For road cut slopes, the variation in dry density is closely related to the moisture content within the slope. As the slope height increases, poor drainage within the slope may lead to an increase in moisture content, thus reducing dry density. Conversely, if the drainage within the slope is good, or if the slope material itself has low water absorption, the dry density will remain stable or increase slightly.

[0111] The void ratio refers to the proportion of void volume within a slope to its total volume. This ratio directly affects the slope's permeability and stability. As slope height increases, the voids within the slope decrease due to material rearrangement and compaction, leading to a lower void ratio. However, if excessive slope height causes a decrease in slope stability and results in geological disasters such as landslides, new voids will form during the landslide process, thus increasing the void ratio.

[0112] To more intuitively understand the relevant trends, in Figure 4 The relationship between slope height and density, dry density, and void ratio is shown in the form of a curve graph, which makes it clearer how specific physical properties change as slope height increases.

[0113] based on Figure 4It is known that there is a complex relationship between the height (or depth) of a road cut slope and its physical properties such as density, dry density, and void ratio. Changes in this relationship are influenced not only by the internal materials and structure of the slope but also by external environmental and geological conditions. Therefore, when designing and constructing road cut slopes, it is necessary to fully consider the influence of these factors to ensure the stability and safety of the slope.

[0114] This analysis examines the relationship between the height (depth) of a roadbed slope and its physical properties, such as moisture content, plastic limit, liquid limit, and plasticity index. For a clearer explanation of these relationships, please refer to [link to relevant documentation]. Figure 5 .

[0115] Moisture content refers to the amount of water in the material of a road cut slope, expressed as a percentage by weight. As the height (depth) of the road cut slope increases, the drainage conditions within the slope become more complex. If there is a poor drainage system within the slope or the material itself has poor permeability, the moisture content within the slope may increase with height. This is because gravity causes groundwater or rainwater to more easily seep into the deeper parts of the slope and become difficult to drain. Conversely, if the slope material has good permeability or there are effective drainage measures, the moisture content will remain stable or decrease slightly.

[0116] Plastic limit and liquid limit are indicators describing the physical state of soil or slope materials after water is added. The plastic limit refers to the water content at which soil begins to become soft enough to undergo plastic deformation; the liquid limit refers to the water content at which soil reaches a fully fluid state. As the height (depth) of a road cut slope increases, if the water content rises, the plastic limit and liquid limit of the road cut slope material will increase accordingly, because more water makes the material easier to deform and flow.

[0117] The plasticity index is the difference between the liquid limit and the plastic limit, and it mainly reflects the plasticity of soil or slope materials within a certain moisture content range. The higher the plasticity index, the stronger the plasticity of the cut slope material, and the easier it is to deform under stress. As the height (depth) of the cut slope increases, if the moisture content increases and the plastic limit and liquid limit increase accordingly, then the plasticity index will also increase. This means that the slope material is more likely to undergo plastic deformation under stress, which may affect the stability of the slope.

[0118] As slope height increases, moisture content tends to rise; the plastic limit and liquid limit curves also show an upward trend with increasing moisture content; due to the increase in plastic and liquid limits, the plasticity index also increases with the increase in cut slope height (depth). Therefore, in practical engineering, it is necessary to comprehensively consider relevant factors to assess the stability and safety of cut slopes.

[0119] To analyze the relationship between the height (depth) of the cut slope and its cohesion and internal friction angle, please refer to [link to relevant documentation]. Figure 6 .

[0120] When analyzing the relationship between the height (depth) of a road cut slope and its cohesion and internal friction angle, it is necessary to focus on how the mechanical properties of the road cut slope material change with the slope depth.

[0121] Cohesion is the attractive force between soil or rock particles due to physical and chemical interactions. In road cut slopes, cohesion plays a crucial role in resisting shear forces and maintaining slope stability. In this embodiment, the cohesion coefficient function is used: It can quickly obtain the cohesion coefficient of different road cut slopes.

[0122] Cohesion varies with the height (depth) of the cut slope and is influenced by various factors. If groundwater or moist conditions are present in the cut slope material, moisture content may increase with depth, leading to a decrease in cohesion. Conversely, if the slope material is dry and tightly compacted, cohesion may remain stable or slightly increase.

[0123] The internal friction angle describes the ability of soil or rock particles to rub against and interlock under shear forces. While the internal friction angle typically doesn't change significantly with increasing slope depth, it also depends on the shape, size, and arrangement of the particles within the slope, as well as the contact area and friction coefficient between them. In practical applications, weak layers or interfaces between different materials exist within the slope, causing the internal friction angle to vary and thus affecting the stability of different slopes.

[0124] based on Figure 6 It can be seen that the cohesion curve fluctuates and decreases with the increase of the cut slope height (depth). This is because as the cut slope height (depth) increases, the internal moisture conditions, compaction degree, and interparticle interactions may change, thus affecting the cohesion. Therefore, in practical engineering, comprehensively considering relevant factors helps to more fully assess the stability and safety of different cut slopes.

[0125] In another alternative embodiment, the third index analysis results are obtained by analyzing the influence relationship and change law between dynamic monitoring information and the specific physical characteristics of the road cut slope.

[0126] Based on the dynamic monitoring information of the road cut slope, the parameter information of the third index layer in the multidimensional analysis system of the road cut slope is extracted. The information of the above index layer includes, but is not limited to, engineering geological information, meteorological and hydrological characteristics, support engineering and greening, rainfall and drainage facilities.

[0127] The engineering geological information mainly includes information such as the geological structure of the slope, soil type, rock type, soil mechanical properties, and groundwater level; meteorological and hydrological characteristics include, but are not limited to, rainfall intensity, rainfall frequency, groundwater level changes, and river flow; meteorological and hydrological conditions are important factors affecting slope stability, especially during the rainy season and floods.

[0128] Support engineering and greening cover the type, location and performance of support structures such as retaining walls, anchors and anti-slide piles, as well as the effectiveness of slope greening such as vegetation cover and soil conservation measures. These are all key factors in assessing slope stability.

[0129] The design and performance of drainage systems within drainage facilities are crucial for reducing the adverse effects of water on slope stability, including the monitoring of surface drainage such as drainage ditches and canals, and underground drainage such as drainage wells and tunnels.

[0130] After extracting the relevant parameter information of the third indicator, in-depth analysis is required to reveal the mutual influence and changing patterns among them. In this embodiment, statistical methods such as correlation coefficients and regression analysis can be used to assess the correlation between different parameters; monitor the changing trends of different indicator parameters over time to identify any potential anomalies or instabilities; and evaluate the degree of influence of different parameters on slope stability to determine the criticality of the parameters.

[0131] Based on the above analysis process, the third indicator analysis results can be obtained. These results should include a comprehensive assessment of slope stability, identification of potential risk points, and recommended maintenance or reinforcement measures, thereby providing a scientific basis for assessing the stability and safety of the slope.

[0132] Furthermore, the analysis method of the multidimensional analysis system for road cut slopes in this embodiment is merely an optional condition. In other embodiments, the analysis method of the multidimensional analysis system for road cut slopes can be adjusted according to the actual situation of the road cut slopes and the goals of slope protection and reinforcement. The core of the multidimensional analysis system for road cut slopes in this embodiment lies in its multidimensionality and comprehensiveness. By adjusting the analysis method, it can be ensured that the present invention can adapt to different types of slopes and different protection and reinforcement goals, enabling the present invention to be widely applied in various engineering practices and meet the application needs in different scenarios.

[0133] S4. Based on the analysis results of the first indicator, the second indicator, and the third indicator, and the dynamic monitoring information, a roadbed slope protection and reinforcement plan is formulated. The specific implementation steps and contents are as follows: The method for protecting and reinforcing road cut slopes based on dynamic monitoring technology also includes setting the index weight coefficients of different index layers in the multidimensional analysis system of road cut slopes according to dynamic monitoring information.

[0134] Setting the index weights for different index layers in the multidimensional analysis system of road cut slopes helps to more accurately assess the stability of road cut slopes, thereby enabling the development of more effective protection and reinforcement measures.

[0135] I. Principles for setting indicator weight coefficients.

[0136] In this embodiment, data-driven settings are based on dynamic monitoring information. The weighting coefficients should be set based on dynamic monitoring data to ensure data accuracy and real-time performance. By collecting and analyzing monitoring data such as deformation, displacement, and stress of the road cut slope during dynamic monitoring, the importance of different indicators can be determined more scientifically. Simultaneously, when setting weighting coefficients, the influence between different indicator layers needs to be comprehensively considered, including but not limited to sliding resistance, slope cross-sectional characteristics, cohesion coefficient, engineering geological conditions, and meteorological and hydrological characteristics.

[0137] As the dynamic monitoring information of road cut slopes is continuously updated and the progress of the project changes, the index weight coefficients also need to be dynamically adjusted to ensure the accuracy and timeliness of the analysis results and provide strong support for subsequent protection and reinforcement work.

[0138] The method for setting the indicator weight coefficients in this embodiment is as follows: One approach is to use expert scoring, inviting experts in relevant fields to score the indicators and determining the weight coefficients based on their experience and judgment. This method is simple and easy to implement, but may be affected by the subjective factors of the experts. Another approach is to analyze the monitoring data using statistical methods, determining the weight coefficients by calculating indicators such as correlation coefficients and regression coefficients. This approach is more objective and scientific, but requires a large amount of data and computational support from the system. A third approach is to train and learn from the monitoring data using machine learning algorithms to automatically determine the weight coefficients. This method can handle large amounts of complex data, improving the accuracy and efficiency of the analysis. The weight coefficients set in this embodiment help to judge and evaluate the stability of different road cut slopes and facilitate the implementation of necessary protective measures for different road cut slopes.

[0139] In this embodiment, the road cut slope is comprehensively evaluated based on the index weight coefficient, the analysis results of the first index, the analysis results of the second index, the analysis results of the third index, and dynamic monitoring information, and the comprehensive evaluation results of the road cut slope are obtained. Based on the comprehensive evaluation results, a road cut slope protection and reinforcement plan is formulated.

[0140] The method for protecting and reinforcing road cut slopes based on dynamic monitoring technology adopts a comprehensive evaluation process. This process combines multiple key elements: index weight coefficients, analysis results of the first index, analysis results of the second index, analysis results of the third index, and real-time dynamic monitoring information. Through comprehensive analysis of relevant elements, a comprehensive and detailed evaluation of the road cut slope is carried out, and the comprehensive evaluation results of different road cut slopes are finally obtained.

[0141] The above comprehensive assessment results serve as an important basis for the subsequent formulation of road cut slope protection and reinforcement schemes. Different road cut slopes have different geological characteristics and stability requirements. Therefore, when formulating protection and reinforcement schemes, it is necessary to fully consider the slope characteristics revealed by the comprehensive assessment results, so as to ensure that different protection and reinforcement measures can solve the specific problems existing in different road cut slopes, that is, to ensure the feasibility and effectiveness of protection and reinforcement measures.

[0142] Dynamic monitoring information played a crucial role in the assessment process. By monitoring various key indicators of the road cut slope in real time, potential safety hazards of the road cut slope can be detected in a timely manner, and corresponding early warning measures can be taken. Once the monitoring value of one or more indicators exceeds the preset safety range, the system can immediately trigger the early warning mechanism to remind relevant personnel to take timely measures and intervene.

[0143] Meanwhile, the embodiment incorporates the reasonable setting of weight coefficients for relevant indicators in the multidimensional analysis system for road cut slopes. Different indicators have varying degrees of influence on slope stability; therefore, during the evaluation process, corresponding weight coefficients are assigned to each indicator based on its importance within the system. This allows for a more accurate reflection of the impact of different key indicators on slope stability during comprehensive evaluation, leading to more scientific evaluation results.

[0144] In summary, the comprehensive evaluation method for road cut slopes in this embodiment not only fully considers multiple key factors, but also makes full use of the advantages of dynamic monitoring information and index weighting coefficients, providing strong support for the formulation of effective protection and reinforcement schemes.

[0145] In an optional embodiment, during the risk warning stage, by performing real-time analysis and processing of monitoring data and combining it with weighting coefficients for risk warning, when the monitoring value of one or more indicators exceeds a preset threshold, the warning device in the road cut slope protection and reinforcement system can automatically issue a warning signal based on the analysis results, reminding relevant personnel to take timely measures for reinforcement.

[0146] In the process of optimizing reinforcement schemes, the design and implementation of existing reinforcement schemes can be optimized based on the magnitude of the weight coefficients and the stability assessment results of the slope. More attention and emphasis can be given to indicators with larger weight coefficients to further ensure the effectiveness and reliability of reinforcement measures.

[0147] Please see Figure 7 In an optional embodiment, to efficiently execute the roadbed slope protection and reinforcement method based on dynamic monitoring technology provided by this invention, this invention also provides a roadbed slope protection and reinforcement system based on dynamic monitoring technology. In this system, input devices, a processor, an output device, and a memory are interconnected. The memory stores a computer program, which includes program instructions. The processor is configured to call the program instructions and execute the specific steps of the relevant embodiments of the roadbed slope protection and reinforcement method based on dynamic monitoring technology provided by this invention. The roadbed slope protection and reinforcement system based on dynamic monitoring technology of this invention has a complete and stable structure, and can efficiently execute the roadbed slope protection and reinforcement method based on dynamic monitoring technology of this invention, thereby improving the overall applicability and practical application capability of this invention.
