Background Technology

[0002] 3D geological modeling of landslides is a new technology that uses computer technology to combine tools such as landslide spatial information management, geological interpretation, spatial analysis and prediction, geostatistics, entity content analysis and graphic visualization in a 3D environment for geological research.

[0003] The relevant landslide 3D geological modeling method utilizes UAV oblique photography, UAV lidar measurements, and borehole data to establish a refined and updatable 3D geological model of the landslide. This includes constructing a 3D model of the landslide surface, constructing a 3D model of the landslide depth, and coupling the surface and depth models. While this technology offers advantages in terms of refinement and real-time performance in landslide 3D modeling, it is highly dependent on survey data, requiring borehole drilling and engineering geological profiles for 3D modeling.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] The technical solution of this application is as follows:

[0051] Firstly, please refer to Figure 1 This application provides a landslide 3D modeling method that integrates stratigraphic lithology and prevention measures, including:

[0056] S5. Data fusion is performed between the three-dimensional model of landslide prevention measures and the three-dimensional model of landslide monitoring results to obtain a three-dimensional landslide model that integrates stratigraphic lithology and prevention measures.

[0057] In S1:

[0058] Please see Figures 6 to 10 In some embodiments, the method for obtaining multiple three-dimensional models of landslide bodies includes: establishing the landslide plane and the spatial location of the sliding surface within the overall slope stratum three-dimensional model containing the landslide boundary, then establishing the spatial location of the boundary around the landslide body, then performing a Boolean operation between the boundary around the landslide body and the overall slope stratum three-dimensional model containing the landslide boundary, and finally obtaining a single landslide body three-dimensional model. By performing the above Boolean operation on multiple landslide bodies respectively, multiple three-dimensional models of landslide bodies can be obtained.

[0059] The process involves first establishing the curved surface of the sliding surface at the bottom of the landslide body. Then, based on the contact relationship between the landslide body and the surrounding rock and soil, the spatial position of the surrounding boundary is established, ensuring consistency with the landslide surface boundary conditions. Finally, each landslide body is defined by its bottom sliding surface and surrounding boundary conditions. Boolean operations are then performed with the overall slope strata 3D model containing the landslide boundary. After the operation, each landslide body is cut into individual blocks to obtain a single landslide body 3D model. Finally, multiple single landslide body 3D models and the overall slope strata 3D model containing the landslide boundary are compared to verify the location of the landslide boundary, landslide body, slip zone, and slip bed. After verification, multiple landslide body 3D models are obtained.

[0060] For example, please refer to Figure 6 In real-world cases, layered slip surfaces are established along weak strata; please refer to [link / reference]. Figure 7 Then, establish the boundary conditions around the landslide body based on the contact relationship between the landslide body and the surrounding rock and soil, ensuring that they match the surface boundary conditions of the landslide; please refer to Figure 8 Finally, each landslide body is defined by its bottom sliding surface and surrounding boundary conditions, and Boolean operations are performed with the overall slope strata 3D model containing the landslide boundaries; please refer to [link to relevant documentation]. Figure 9 After calculation, each landslide body is cut into individual blocks to obtain a single landslide body 3D model. Finally, multiple single landslide body 3D models and a complete slope strata 3D model including the landslide boundary are combined to verify the location of the landslide boundary, landslide body, slip zone, and slip bed; please refer to [link to relevant documentation]. Figure 10 This yields multiple 3D models of sliding bodies; in this example, there are five 3D models of sliding bodies.

[0061] Please see Figures 3 to 5 Furthermore, methods for obtaining a three-dimensional model of the overall slope strata including landslide boundaries include:

An improved kriging method is used to interpolate between the profiles, which better balances accuracy and the spatial distribution characteristics of the soil and rock layers. The real digital elevation model of the slope surface after vegetation removal is obtained by using UAV lidar terrain-following flight technology. The slope surface is established using the real digital elevation model. The real digital elevation model is then spatially matched with the three-dimensional model of the engineering geological profile to establish an overall three-dimensional model of the slope strata.

First, the cross-sectional dimensions of the treatment project were determined. After modeling according to the actual dimensions, a three-dimensional spatial trajectory was used for layout processing to establish a three-dimensional model of the landslide treatment project. Boolean operations were then performed between the treatment project and the three-dimensional models of the slope surface and depth to achieve seamless integration between the treatment project and the surface.

[0120] Test case

[0121] Please see Figure 17 This paper applies the method to a landslide to obtain a three-dimensional landslide model that integrates stratigraphic lithology and prevention measures. The cumulative deformation data from GNSS monitoring of landslide surfaces in practical cases from 2014-2022 are combined with the three-dimensional landslide model integrating stratigraphic lithology and prevention measures. The combined surface deformation and displacement direction at each surface deformation monitoring point are spatially calculated, and the vector direction is calculated and projected onto the surface of the three-dimensional geological model. Then, the surface deformation data at each landslide location is spatially interpolated using a weighted inverse averaging method to obtain a surface displacement and deformation cloud map of the landslide.

[0122] The surface deformation generally exhibits a "larger deformation in the north and smaller deformation in the south" pattern, with the overall deformation direction being 350°. This indicates that the landslide formation mechanisms differ across different areas. The front area of ​​the Ertai landslide showed the greatest deformation, with a cumulative deformation of 440-3142 mm from 2014 to the end of 2022. This application clearly demonstrates the spatial matching and displacement of surface deformation, making the landslide monitoring results readily apparent. Compared to traditional landslide monitoring data, which is expressed through arrow sizes on two-dimensional profiles or time-series deformation curves of individual monitoring points, this application achieves a three-dimensional spatial representation of the monitoring data, significantly enhancing the presentation of professional monitoring results.

[0123] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
