Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a capillary reinforcement construction method for high slopes. Background Technology

[0002] Current methods for backfilling high slopes involve surcharge preloading at a certain slope to achieve a certain preload value and stabilize the slope. However, during rainfall, changes in soil moisture conditions can easily lead to a decrease in effective stress within the slope, reducing its stability. Existing slope drainage construction methods typically employ multiple sets of drainage devices with complex and costly pre-embedded processes to achieve internal drainage, resulting in high maintenance costs and reduced economic benefits. Therefore, there is an urgent need for a simple, low-cost capillary reinforcement construction method suitable for internal slope drainage.

[0003] Chinese Patent Publication No. CN113605357B discloses a drainage structure and its construction method suitable for slopes. The drainage structure includes an upper structure and a lower structure, both composed of an outer pipe and an inner pipe. The outer and inner pipes are fixedly connected by a series of evenly distributed long bolts, forming a concentric double-layer structure. Both the outer and inner pipes of the upper structure are provided with permeable holes. Inclined water-guiding plates are provided in the transition area between the upper and lower structures. This drainage structure utilizes the capillary action of the capillary drainage system to alleviate clogging, allowing the drainage pipe to continue functioning even after clogging. Furthermore, the inner and outer pipe walls and rigid plastic support strips effectively protect the capillary drainage system from deformation and damage. However, this drainage structure and its construction method for slopes still suffer from the problem of requiring multiple sets of drainage devices with complex and costly pre-embedded processes to achieve internal slope drainage, leading to high maintenance costs and relatively low economic efficiency. Summary of the Invention

[0004] Therefore, this invention provides a capillary reinforcement construction method for high slopes to overcome the problem that the high cost of multiple drainage devices with complex pre-embedded processes in the prior art leads to high maintenance costs and relatively low economic benefits.

[0005] To achieve the above objectives, the present invention provides a method for capillary reinforcement of high slopes, comprising:

[0006] Step S1: Determine the parameters of the high slope based on preset requirements, hydrological conditions, and geological conditions. The parameters of the high slope include the base area of ​​the high slope, the slope gradient, and the height of the high slope.

[0007] Step S2: Establish a geographical environment model for a preset year. Based on the parameters of the high slope, determine whether the preset high slope structural strength meets the preset strength standard by observing the changes in the high slope structural strength in the high slope geographical environment model. Based on the judgment result of the preset high slope structural strength and the preset strength standard, make corresponding adjustments to the preset high slope structure.

[0008] Step S3: Determine the slope protection method of the high slope based on the adjusted preset high slope structure, and learn the corresponding geographical environment data of the preset high slope structure and slope protection method.

[0009] In step S1, the height, slope, and base area of ​​the high slope are determined based on preset requirements, hydrological conditions, and geological conditions. Specifically, the height of the high slope is determined based on preset requirements, the physical and mechanical parameters of the high slope soil are collected, and the slope and base area of ​​the high slope are determined in combination with the hydrological and hydrogeological conditions at the geographical location of the high slope.

[0010] In step S2, geographical environment data for a preset year is collected at the location of the high slope, and a corresponding geographical environment model is established. The parameters of the high slope are entered into the geographical environment model for the preset year. Based on the changes in the high slope parameters under the geographical environment of the preset year, it is determined whether the structural strength of the high slope in the simulated environment meets the preset standard. Simultaneously, based on the comparison between the structural strength of the high slope in the simulated environment and its corresponding preset standard, corresponding adjustments are made to the preset high slope structure.

[0011] The geographic environmental data for the preset year includes humidity variation data, precipitation data, wind force level data, earthquake magnitude data, and temperature variation data for the preset year.

[0012] Specifically, the humidity variation data for a preset year is used to determine the soil moisture inside the high slope and its impact on the high slope; the precipitation data for a preset year is used to determine the impact of the level and frequency of drought and flood disasters suffered by the high slope on the high slope; the wind force data for a preset year is used to determine the wind force level suffered by the high slope and its impact on the high slope; the earthquake magnitude data for a preset year is used to determine the earthquake magnitude suffered by the high slope and its impact on the high slope; and the temperature variation data for a preset year is used to determine the soil temperature inside the high slope and its impact on the high slope.

[0013] Specifically, the combined effects of extreme humidity and temperature changes can cause irreversible and permanent damage to the structural strength of high slopes, and the natural phenomena caused by these combined effects include frost heave, drought, and thaw settlement.

[0014] In step S2, the pre-set high slope structure includes high-strength drainage capillaries, a stone slag protective layer, and earthwork. The high-strength drainage capillaries are respectively installed in the stone slag protective layer and outside the high slope. The high-strength drainage capillaries in the stone slag protective layer and outside the high slope are interconnected. The sidewalls of the high-strength drainage capillaries are interconnected to form a mesh planar structure. The mesh shape of the mesh planar structure is rhomboid. The high-strength drainage capillaries are provided with openings. The stone slag protective layer is installed in the earthwork.

[0015] In step S2, the pre-set construction sequence of the high slope structure includes: compacting the foundation by rolling or leveling the surface by chiseling; laying a stone slag protective layer until its area matches the bottom area parameters of the high slope; installing a mesh of high-strength drainage capillary tubes in the stone slag protective layer; rolling backfill soil on top of the stone slag protective layer; laying another stone slag protective layer and installing a mesh of high-strength drainage capillary tubes in the stone slag protective layer; rolling backfill soil on top of the stone slag protective layer; laying a stone slag protective layer on the soil and installing high-strength drainage capillary tubes in the stone slag protective layer; stacking the soil in the above sequence until the top height of the soil matches the height parameters of the high slope; adjusting the slope of the high slope to match the slope parameters; laying high-strength drainage capillary tubes outside the slope protection; and setting drainage grooves at the bottom of the outer perimeter of the high slope.

[0016] In step S2, the high-strength drainage capillary tube has an inverted funnel-shaped opening with a smaller outer diameter and a larger inner diameter. The preset diameter of the large funnel-shaped opening on the inner wall of the high-strength drainage capillary tube is 1.3 mm, and the preset diameter of the small funnel-shaped opening on the outer wall of the high-strength drainage capillary tube is 0.7 mm. The preset spacing between the openings of the same high-strength drainage capillary tube is 50 cm. The preset area of ​​the diamond mesh of the high-strength drainage capillary tube is 10 square centimeters. The preset thickness of the stone slag protective layer is 10 cm. The preset thickness of the backfill soil after compaction is 350 cm. The preset particle size of the stone slag in the stone slag protective layer is 3 mm to 5 mm. The preset compaction coefficient of the backfill soil after compaction is 0.95. The high-strength drainage capillary tubes are laid at equal intervals in the stone slag protective layer. The minimum distance between the high-strength drainage capillary tube and the upper and lower edges of the stone slag protective layer is 1 cm.

[0017] In step S2, the preset parameters of the high slope are entered into the geographic environment model for a preset year. Based on the changes in the high slope parameters under the geographic environment of the preset year, it is determined whether the structural strength of the high slope in the simulated environment meets the preset standards.

[0018] In a simulated environment, when the structural strength of a high slope in a preset year does not meet the preset structural strength standard, the influence of the geographical environment data for the preset year on the preset high slope structural strength is assessed, and corresponding adjustments are made to the high slope structure.

[0019] When the required resistance level for humidity variation data in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the stone ballast protective layer, the number of layers of the mesh high-strength drainage capillary pipe, the earthwork thickness, and the earthwork compaction coefficient.

[0020] If the peak-to-valley difference of the humidity change curve exceeds the preset difference value or the valley value of the humidity change curve is lower than the preset threshold, it is necessary to reduce the thickness of the stone slag protective layer, reduce the number of layers of high-strength mesh drainage capillary pipes laid within the stone slag protective layer, and increase the soil thickness and soil compaction coefficient to reduce the humidity exchange between the inside and outside environment of the high slope and maintain a stable humidity state inside the high slope.

[0021] If the peak value of the humidity change curve exceeds the preset threshold, the thickness of the stone slag protective layer needs to be increased, the number of layers of high-strength mesh drainage capillary pipes inside the stone slag protective layer needs to be increased, and the soil compaction coefficient needs to be increased to improve ventilation inside the high slope and facilitate the rapid discharge of humidity inside the high slope.

[0022] When the required resistance level for temperature changes in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the gravel protective layer, the number of layers of the mesh high-strength drainage capillary pipe, the earthwork thickness, and the earthwork compaction coefficient.

[0023] If the peak-to-valley difference of the temperature change curve exceeds the preset difference value or the valley value of the temperature change curve is lower than the preset threshold, it is necessary to increase the thickness of the stone slag protective layer, reduce the number of layers of high-strength mesh drainage capillary pipes laid within the stone slag protective layer, and increase the soil thickness and soil compaction coefficient. This will reduce the impact of deformation caused by large temperature changes on the preset high slope structural strength and maintain a stable internal temperature state for the high slope.

[0024] If the peak value of the temperature change curve exceeds the preset threshold, the thickness of the stone slag protective layer should be reduced, the number of layers of high-strength mesh drainage capillary pipes inside the stone slag protective layer should be reduced, and the earthwork thickness should be increased to reduce the humidity exchange between the inside and outside environment of the high slope and prevent the effects of frost heave and thaw settlement on the preset high slope structural strength.

[0025] When the required resistance level for precipitation data in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the gravel protective layer, the number of layers of mesh high-strength drainage capillary pipes, the earthwork thickness, and the earthwork compaction coefficient.

[0026] If the trough of the precipitation variation curve is lower than the preset threshold, the thickness of the gravel protective layer should be reduced, and the number of layers of high-strength mesh drainage capillaries within the gravel protective layer should be reduced to increase the impact of dryness or drought on the preset high slope structural strength, thus keeping the internal humidity of the high slope in a stable state.

[0027] If the peak-to-valley difference of the precipitation change curve exceeds the preset difference or the peak value of the precipitation change curve exceeds the preset threshold, the thickness of the stone slag protective layer needs to be increased, the number of layers of mesh high-strength drainage capillary pipes inside the stone slag protective layer needs to be increased, and the soil compaction coefficient needs to be increased to improve the drainage speed of the moisture inside the high slope.

[0028] When the wind force level required by the geographical environmental data for a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the earthwork, the earthwork compaction coefficient, and the number of layers of high-strength drainage capillary mesh with stone slag protective layer.

[0029] If the peak-to-valley difference of the wind force level variation curve exceeds the preset difference value or the peak value of the wind force level variation curve exceeds the preset threshold, it is necessary to reduce the thickness of the ballast protective layer, increase the number of layers of high-strength mesh drainage capillary pipes inside the ballast protective layer, increase the number of layers of high-strength mesh drainage capillary pipes outside the high slope, increase the thickness of the earthwork and the earthwork compaction coefficient, and improve the wind resistance level of the high slope.

[0030] If the valley value of the wind force level change curve is lower than the preset threshold, the thickness of the ballast protective layer needs to be increased and the number of layers of mesh high-strength drainage capillary pipes inside the ballast protective layer needs to be reduced.

[0031] When the earthquake resistance level required by the geographical environment data for a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to increase the thickness of the earthwork, the earthwork compaction coefficient, and the number of layers of high-strength drainage capillary mesh on the outside of the high slope, and to set up corresponding reinforced concrete structural columns inside the high slope to improve the earthquake resistance level of the high slope.

[0032] Specifically, the selection of the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient adopts a priority-based method. Specifically, the geographic environmental data is sorted in descending order of priority: earthquake level data > precipitation level data > humidity level data > temperature level data > wind force level data. That is, the selection of the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient is performed sequentially according to the priority of the geographic environmental data. If only the preset number of laying layers and preset stone ballast thickness corresponding to the earthquake level data can be satisfied, the selection will be delayed. If the earthquake magnitude, soil thickness, and compaction coefficient are the only parameters that can be satisfied, then the preset number of laying layers, preset stone thickness, preset soil thickness, and preset compaction coefficient should be selected based on the preset data corresponding to the earthquake magnitude and precipitation magnitude data. If only the preset number of laying layers, preset stone thickness, preset soil thickness, and preset compaction coefficient corresponding to the earthquake magnitude and precipitation magnitude data can be satisfied, then the preset number of laying layers, preset stone thickness, preset soil thickness, and preset compaction coefficient should be selected based on the preset data corresponding to the earthquake magnitude and precipitation magnitude data. This process continues, selecting the preset data that best satisfies the geographical environment data in order of priority.

[0033] In step S2, when the structural strength of the high slope in the simulated environment meets the preset structural strength standard in a preset year, the influence of the geographical environment data of the preset year on the preset high slope structural strength is determined, and the structure of the high slope is adjusted accordingly.

[0034] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the humidity change data in the geographical environment data of the preset year, it is necessary to reduce the thickness of the stone slag protective layer, reduce the number of layers of mesh high-strength drainage capillary pipes in the stone slag protective layer, increase the soil thickness, and reduce the soil compaction coefficient in order to reduce the cost of the high slope.

[0035] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the temperature change data in the geographical environment data of the preset year, it is necessary to increase the thickness of the stone slag protective layer and reduce the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer in order to reduce the cost of the high slope.

[0036] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the precipitation data in the geographic environment data of the preset year, the thickness of the stone slag protective layer and the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer should be reduced.

[0037] When the strength level corresponding to the preset high slope structure exceeds the wind force level required by the geographical environment data of the preset year, it is necessary to increase the thickness of the stone slag protective layer, reduce the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer, and increase the earthwork thickness.

[0038] When the strength level corresponding to the preset high slope structure exceeds the earthquake resistance level required by the geographical environment data of the preset year, the earthwork compaction coefficient and the number of layers of high-strength drainage capillary mesh on the outside of the high slope need to be reduced.

[0039] In step S3, the slope protection method for the high slope is determined based on the strength level corresponding to the adjusted preset high slope structure. The slope protection methods include setting up protective netting, planting vegetation, setting up retaining walls, and setting up a reinforced concrete framework for the slope.

[0040] When the required resistance level for humidity variation data in the geographic environment data of a preset year exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0041] When the required resistance level for temperature changes in the geographic environmental data of a preset year exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection is not required.

[0042] When the required resistance level for precipitation data in the preset year's geographical environment data exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0043] When the wind force level data in the preset year's geographical environment data requires a resistance level that exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0044] When the earthquake resistance level required by the geographic environmental data for a preset year exceeds the corresponding strength level in the preset high slope structure after adjustment, slope protection must be used and the corresponding slope protection method must be selected.

[0045] In step S3, the geographic environment data corresponding to the preset high slope structure and slope protection method are learned, and the high slope structure adjustment is carried out by real-time updating the high slope post-maintenance data and the corresponding geographic environment data. The preset high slope structure strength change is predicted and an early warning is issued in real time. The next adjustment is optimized based on the impact of the geographic environment data on the high slope structure strength and its corresponding adjustment.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by using a specially designed pre-designed high slope structure to increase the discharge of capillary water into the high slope, the internal drainage of the high slope is achieved, thereby improving the stability of the earthwork slope.

[0047] Furthermore, by adding specially designed high-strength drainage capillary tubes within the earthwork, capillary action and siphon effect can be utilized to accelerate the drainage time of capillary water within the earthwork. At the same time, the special structure of the high-strength drainage capillary tubes can reinforce the interior of the stone slag protective layer, stabilizing the stone slag protective layer, improving the stability of the earthwork slope, reducing construction costs, and simplifying the construction process.

[0048] Furthermore, by setting a stone slag protective layer around the high-strength drainage capillary tubes in the earthwork, impurities in the water can be filtered during the drainage of the high-strength drainage capillary tubes, preventing the opening of the high-strength drainage capillary tubes from becoming blocked and thus slowing down the capillary water transport of the earthwork slope. This improves the stability of the earthwork slope, reduces the later maintenance cost, and improves economic benefits.

[0049] Secondly, by establishing a geographical environment model for a preset year based on the geographical environment data of a preset location within a preset year, simulation experiments can be conducted on high slopes with preset parameters at the preset location. The results of these experiments can then be used to determine what adjustments should be made to the preset high slope structure. This allows for an early prediction of whether the service life of the preset high slope structure at the preset location meets the design requirements, and corresponding adjustments can be made accordingly.

[0050] Third, by learning from the geographical environment data corresponding to the preset high slope structure and slope protection methods, and then updating the high slope post-maintenance data and corresponding geographical environment data in real time, the structural adjustment of the high slope can be carried out through deep learning. This can predict changes in the preset high slope structural strength and issue early warnings in real time. This can make the structural adjustment of the high slope at the preset location and geographical environment type more accurate, and thus make the adjustment of the preset high slope structural strength more accurate. This makes the high slope reinforcement construction more intelligent, and reduces costs and improves economic efficiency while meeting design requirements. Attached Figure Description

[0063] Please see Figure 1 As shown, this is a structural schematic diagram of the capillary reinforcement construction method for high slopes according to an embodiment of the present invention. This embodiment includes:

[0064] Step S1: Determine the parameters of the high slope based on preset requirements, hydrological conditions, and geological conditions. The parameters of the high slope include the base area of ​​the high slope, the slope gradient, and the height of the high slope.

[0065] Step S2: Establish a geographical environment model for a preset year. Based on the parameters of the high slope, determine whether the preset high slope structural strength meets the preset strength standard by observing the changes in the high slope structural strength in the high slope geographical environment model. Based on the judgment result of the preset high slope structural strength and the preset strength standard, make corresponding adjustments to the preset high slope structure.

[0066] Step S3: Determine the slope protection method of the high slope based on the adjusted preset high slope structure, and learn the corresponding geographical environment data of the preset high slope structure and slope protection method.

[0067] In step S1, the height, slope, and base area of ​​the high slope are determined based on preset requirements, hydrological conditions, and geological conditions. Specifically, the height of the high slope is determined based on preset requirements, the physical and mechanical parameters of the high slope soil are collected, and the slope and base area of ​​the high slope are determined in combination with the hydrological and hydrogeological conditions at the geographical location of the high slope.

[0068] In step S2, geographical environment data for a preset year is collected at the location of the high slope, and a corresponding geographical environment model is established. The parameters of the high slope are entered into the geographical environment model for the preset year. Based on the changes in the high slope parameters under the geographical environment of the preset year, it is determined whether the structural strength of the high slope in the simulated environment meets the preset standard. Simultaneously, based on the comparison between the structural strength of the high slope in the simulated environment and its corresponding preset standard, corresponding adjustments are made to the preset high slope structure.

[0069] The geographic environmental data for the preset year includes humidity variation data, precipitation data, wind force level data, earthquake magnitude data, and temperature variation data for the preset year.

[0070] In this embodiment, humidity variation data for a preset year is used to determine the soil moisture inside the high slope and its impact on the high slope; precipitation data for a preset year is used to determine the impact of the level and frequency of drought and flood disasters suffered by the high slope on the high slope; wind force data for a preset year is used to determine the wind force level suffered by the high slope and its impact on the high slope; earthquake magnitude data for a preset year is used to determine the earthquake magnitude suffered by the high slope and its impact on the high slope; and temperature variation data for a preset year is used to determine the soil temperature inside the high slope and its impact on the high slope.

[0071] Specifically, the combined effects of extreme humidity and temperature changes can cause irreversible and permanent damage to the structural strength of high slopes, and the natural phenomena caused by these combined effects include frost heave, drought, and thaw settlement.

[0072] In step S2, the pre-set high slope structure includes high-strength drainage capillaries, a stone slag protective layer, and earthwork. The high-strength drainage capillaries are respectively installed in the stone slag protective layer and outside the high slope. The high-strength drainage capillaries in the stone slag protective layer and outside the high slope are interconnected. The sidewalls of the high-strength drainage capillaries are interconnected to form a mesh planar structure. The mesh shape of the mesh planar structure is rhomboid. The high-strength drainage capillaries are provided with openings. The stone slag protective layer is installed in the earthwork.

[0073] In step S2, the pre-set construction sequence of the high slope structure includes: compacting the foundation by rolling or leveling the ground surface by chiseling; laying a stone slag protective layer until its area matches the bottom area parameters of the high slope; installing a mesh of high-strength drainage capillary tubes in the stone slag protective layer; rolling backfill soil above the stone slag protective layer to the preset compaction coefficient; laying another stone slag protective layer and installing a mesh of high-strength drainage capillary tubes in the stone slag protective layer; rolling backfill soil above the stone slag protective layer; laying a stone slag protective layer on the soil and installing high-strength drainage capillary tubes in the stone slag protective layer; stacking the soil in the above sequence until the top height of the soil matches the height parameters of the high slope; adjusting the slope of the high slope to match the slope parameters; laying high-strength drainage capillary tubes outside the slope protection; and setting drainage grooves at the bottom of the outer perimeter of the high slope.

[0074] In step S2, the high-strength drainage capillary tube has an inverted funnel-shaped opening with a smaller outer diameter and a larger inner diameter. The preset diameter of the large funnel-shaped opening on the inner wall of the high-strength drainage capillary tube is 1.3 mm, and the preset diameter of the small funnel-shaped opening on the outer wall of the high-strength drainage capillary tube is 0.7 mm. The preset spacing between the openings of the same high-strength drainage capillary tube is 50 cm. The preset area of ​​the diamond mesh of the high-strength drainage capillary tube is 10 square centimeters. The preset thickness of the stone slag protective layer is 10 cm. The preset thickness of the backfill soil after compaction is 350 cm. The preset particle size of the stone slag in the stone slag protective layer is 3 mm to 5 mm. The preset compaction coefficient of the backfill soil after compaction is 0.95. The high-strength drainage capillary tubes are laid at equal intervals in the stone slag protective layer. The minimum distance between the high-strength drainage capillary tube and the upper and lower edges of the stone slag protective layer is 1 cm.

[0075] In step S2, the preset parameters of the high slope are entered into the geographic environment model for a preset year. Based on the changes in the high slope parameters under the geographic environment of the preset year, it is determined whether the structural strength of the high slope in the simulated environment meets the preset standards.

[0076] In a simulated environment, when the structural strength of a high slope in a preset year does not meet the preset structural strength standard, the influence of the geographical environment data for the preset year on the preset high slope structural strength is assessed, and corresponding adjustments are made to the high slope structure.

[0077] When the required resistance level for humidity variation data in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the stone ballast protective layer, the number of layers of the mesh high-strength drainage capillary pipe, the earthwork thickness, and the earthwork compaction coefficient.

[0078] If the peak-to-valley difference of the humidity change curve exceeds the preset difference value or the valley value of the humidity change curve is lower than the preset threshold, the thickness of the ballast protective layer needs to be reduced, the number of layers of high-strength mesh drainage capillary pipes inside the ballast protective layer needs to be reduced, and the soil thickness needs to be increased to reduce the soil compaction coefficient, reduce the humidity exchange between the inside and outside environment of the high slope, and maintain a stable humidity state inside the high slope.

[0079] If the peak value of the humidity change curve exceeds the preset threshold, the thickness of the stone slag protective layer needs to be increased, the number of layers of high-strength mesh drainage capillary pipes inside the stone slag protective layer needs to be increased, and the soil compaction coefficient needs to be increased to improve ventilation inside the high slope and facilitate the rapid discharge of humidity inside the high slope.

[0080] When the required resistance level for temperature changes in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the gravel protective layer, the number of layers of the mesh high-strength drainage capillary pipe, the earthwork thickness, and the earthwork compaction coefficient.

[0081] If the peak-to-valley difference of the temperature change curve exceeds the preset difference value or the valley value of the temperature change curve is lower than the preset threshold, it is necessary to increase the thickness of the stone slag protective layer, reduce the number of layers of high-strength mesh drainage capillary pipes laid within the stone slag protective layer, and increase the soil thickness and soil compaction coefficient. This will reduce the impact of deformation caused by large temperature changes on the preset high slope structural strength and maintain a stable internal temperature state for the high slope.

[0082] If the peak value of the temperature change curve exceeds the preset threshold, the thickness of the stone slag protective layer should be reduced, the number of layers of high-strength mesh drainage capillary pipes inside the stone slag protective layer should be reduced, and the earthwork thickness should be increased to reduce the humidity exchange between the inside and outside environment of the high slope and prevent the effects of frost heave and thaw settlement on the preset high slope structural strength.

[0083] When the required resistance level for precipitation data in the geographic environment data of a preset year exceeds the corresponding strength level in the preset high slope structure, it is necessary to change the thickness of the gravel protective layer, the number of layers of mesh high-strength drainage capillary pipes, the earthwork thickness, and the earthwork compaction coefficient.

[0084] If the trough of the precipitation variation curve is lower than the preset threshold, the thickness of the gravel protective layer should be reduced, and the number of layers of high-strength mesh drainage capillaries within the gravel protective layer should be reduced to increase the impact of dryness or drought on the preset high slope structural strength, thus keeping the internal humidity of the high slope in a stable state.

[0120] In this embodiment, the selection of the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient adopts a priority-based method. Specifically, the geographic environmental data is sorted in descending order of priority: earthquake level data > precipitation level data > humidity level data > temperature level data > wind force level data. That is, the selection of the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient is performed sequentially according to the priority of the geographic environmental data. If only the preset number of laying layers and preset stone ballast thickness corresponding to the earthquake level data can be satisfied, the selection will be delayed. For the thickness, preset earthwork thickness, and preset compaction coefficient, the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient should be selected based on the preset data corresponding to the earthquake level data. If only the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient corresponding to the earthquake level data and precipitation level data can be satisfied, then the preset number of laying layers, preset stone ballast thickness, preset earthwork thickness, and preset compaction coefficient should be selected based on the preset data corresponding to the earthquake level data and precipitation level data, and so on, selecting the preset data that best satisfies the geographical environment data in priority order.

[0121] In step S2, when the structural strength of the high slope in the simulated environment meets the preset structural strength standard in a preset year, the influence of the geographical environment data of the preset year on the preset high slope structural strength is determined, and the structure of the high slope is adjusted accordingly.

[0122] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the humidity change data in the geographical environment data of the preset year, it is necessary to reduce the thickness of the stone slag protective layer, reduce the number of layers of mesh high-strength drainage capillary pipes in the stone slag protective layer, increase the soil thickness, and reduce the soil compaction coefficient in order to reduce the cost of the high slope.

[0123] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the temperature change data in the geographical environment data of the preset year, it is necessary to increase the thickness of the stone slag protective layer and reduce the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer in order to reduce the cost of the high slope.

[0124] When the strength level corresponding to the preset high slope structure exceeds the resistance level required by the precipitation data in the geographic environment data of the preset year, the thickness of the stone slag protective layer and the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer should be reduced.

[0125] When the strength level corresponding to the preset high slope structure exceeds the wind force level required by the geographical environment data of the preset year, it is necessary to increase the thickness of the stone slag protective layer, reduce the number of layers of mesh high-strength drainage capillary pipes laid in the stone slag protective layer, and increase the earthwork thickness.

[0126] When the strength level corresponding to the preset high slope structure exceeds the earthquake resistance level required by the geographical environment data of the preset year, the earthwork compaction coefficient and the number of layers of high-strength drainage capillary mesh on the outside of the high slope need to be reduced.

[0127] In this embodiment, the multiple layers of high-strength drainage capillaries within the slag protective layer are connected by vertical high-strength drainage capillaries.

[0128] In this embodiment, the resistance level corresponding to the final adjusted values ​​of the stone slag protective layer thickness, the number of layers of mesh high-strength drainage capillary pipes, the earthwork thickness, and the earthwork compaction coefficient is adjusted according to the resistance level required by the preset high slope structure in the geographical environment data of the preset year. That is, the resistance level corresponding to the final adjusted values ​​of the stone slag protective layer thickness, the number of layers of mesh high-strength drainage capillary pipes, the earthwork thickness, and the earthwork compaction coefficient is greater than or equal to the resistance level required by the geographical environment data of the preset year.

[0129] In step S3, the slope protection method for the high slope is determined based on the strength level corresponding to the adjusted preset high slope structure. The slope protection methods include setting up protective netting, planting vegetation, setting up retaining walls, and setting up a reinforced concrete framework for the slope.

[0130] When the required resistance level for humidity variation data in the geographic environment data of a preset year exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0131] When the required resistance level for temperature changes in the geographic environmental data of a preset year exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection is not required.

[0132] When the required resistance level for precipitation data in the preset year's geographical environment data exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0133] When the wind force level data in the preset year's geographical environment data requires a resistance level that exceeds the corresponding strength level in the adjusted preset high slope structure, slope protection must be used and the corresponding slope protection method must be selected.

[0134] When the earthquake resistance level required by the geographic environmental data for a preset year exceeds the corresponding strength level in the preset high slope structure after adjustment, slope protection must be used and the corresponding slope protection method must be selected.

[0135] In step S3, the geographic environment data corresponding to the preset high slope structure and slope protection method are learned, and the high slope structure adjustment is carried out by real-time updating the high slope post-maintenance data and the corresponding geographic environment data. The preset high slope structure strength change is predicted and an early warning is issued in real time. The next adjustment is optimized based on the impact of the geographic environment data on the high slope structure strength and its corresponding adjustment.

[0136] In this embodiment, the establishment of the geographical environment model, the determination of the strength and changes of the preset high slope structure, the adjustment of the preset high slope structure, the adjustment of the slope protection method of the high slope, and the learning of the adjustment of the preset high slope structure are all automatically completed by the software of the AI ​​learning unit.

[0147] When the earthquake angle δ is at α i ~90°+α i At that time, M S =M SJ +M ES ,

[0148] When the earthquake angle δ is at 90°+α i ~180°+α i At that time, M S =M SJ -M ED ,

[0149] When the earthquake angle δ is at 180°+α i ~270°+α i At that time, M S =M SJ -M ED +M ES ,
