[0002] The current slope anchor cable support measures usually adopt the form of large-scale full slope layout, that is, the anchor cable support structure is arranged on the slope surface in a large area to improve the stability of the slope. However, the large-scale arrangement of prestressed anchor cables to support the entire slope will cause a waste of resources. Therefore, anchor cable support measures are only used for local unstable areas of the slope, and soil nail structures are used for shallow reinforcement in other areas. This can not only ensure the overall stability of the slope, but also minimize the waste of support resources and promote resource conservation and efficient utilization. How to design the anchor cable support system for the unstable area of ​​the slope is a difficult problem that needs to be solved in this field. Summary of the invention

[0039] Embodiment 1:

[0040] This embodiment provides a method for designing a slope anchor cable support system.

[0041] See also Figure 1 , the figure shows that the method includes:

[0042] S1. Obtaining geological information and material parameters of the slope to be predicted and the trained point safety factor prediction model;

[0043] Specifically, the step S1 includes:

[0044] S11. Obtaining first information of a plurality of slopes, and constructing a corresponding slope numerical model using the first information, wherein the first information includes geological information and material parameters;

[0045] In this embodiment, geological information of the slope is obtained through on-site investigation, satellite remote sensing technology, and drone photography technology, including slope aspect, slope elevation, slope gradient, stratum information, hydrological conditions, slope shape, and other information;

[0046] In this embodiment, the material parameters of the slope rock and soil are obtained by using methods such as field tests or indoor tests, including density, elastic modulus, internal friction angle, cohesion, Poisson's ratio, shear modulus, dilatancy angle, porosity, water content, etc.

[0047] Specifically, the step S11 includes:

[0048] S111. Based on the geological information, a three-dimensional model of the slope is constructed using three-dimensional modeling software, such as Figure 2 As shown;

[0049] S112. Grid the three-dimensional geological model to generate a three-dimensional grid model of the slope, such as Figure 3 As shown;

[0050] S113. Import the three-dimensional mesh model of the slope into simulation software, such as FLAC 3D software, group the slope body and the underlying bedrock and assign actual material parameters to the slope to construct a numerical model of the slope, such as Figure 4 shown.

[0051] S12. Calculate the second information of each slope using the slope numerical model, the second information including the landslide area and its point safety factor, and construct a data sample set using the first information as an input label and the second information as an output label;

[0052] Specifically, the slope numerical model test was carried out based on the constructed slope numerical model to simulate the slope instability process and obtain the landslide area, including the landslide shape and sliding surface position, such as Figure 5 As shown;

[0053] The point safety factor of the slope is calculated based on existing algorithms, such as the point safety factor method, transfer coefficient method, simplified Bishop method, etc.

[0054] The first information and the second information of the slope are combined to establish a data sample set, which is divided according to a 4:1 ratio, with 80% of the samples used as a training set and 20% of the samples used as a test set.

[0055] S13. Build a BP neural network model, use the data sample set to train and test the BP neural network model, and obtain a point safety factor prediction model.

[0056] Based on the above embodiments, the method further includes:

[0057] S2. Input the geological information and material parameters of the slope to be predicted into the point safety factor prediction model to obtain the predicted landslide area and its point safety factor, such as Figure 6 As shown;

[0058] Based on the above embodiments, the method further includes:

[0059] S3. judging the stability of the predicted landslide area according to the point safety factor, and considering the predicted landslide area with a point safety factor less than a preset threshold as an unstable area;

[0060] Specifically, the preset threshold of 1.3 is used as the stability state judgment standard, the predicted landslide area with a point safety factor greater than 1.3 is regarded as a stable area, the predicted landslide area with a point safety factor greater than 1.2 and less than 1.3 is regarded as an understable area, and the predicted landslide area with a point safety factor less than 1.2 is regarded as an unstable area.

[0061] In this embodiment, based on the stability state of each range of the slope body that has been divided, soil nails or anchor cables need to be arranged according to different stability states to reinforce the slope, such as Figure 7 As shown. When the stability state of the landslide area is unstable, anchor cables need to be arranged to reinforce the slope. When the stability state of the landslide area is unstable, soil nails need to be arranged to reinforce the slope. When the stability state of the landslide area is stable, no reinforcement is performed. In the present invention, an anchor cable support system is designed for the unstable area that has been divided.

[0081] ΔE i =N i sinα i -T fi cosα i =(w i +ΔX i )tanα i -T fi secα i ;

[0082] Where ΔE i is the resultant normal force between soil strips i.

[0089]

[0090] S44. Iteratively solving the point safety factor calculation model to calculate the local concentrated force required for each soil strip when the point safety factor of the slope reaches a preset threshold.
