Analysis of the Failure Pattern of Shallow Bedding Rock Landslide Based on ANSYS Sofware——Take the 7.01 Landslide in Lihua Township,Dafang County as an example
When judging the failure mode of shallow-layer rock landslide,it is often affected by the man-made engineering slope cutting factors at the exit of landslide shear,and it is difficult to determine the traction type or the passing type,and even the judgment is wrong.In this paper,on the basis of collecting background data and mapping landslide geological hazards,it use Auto-CAD software to reconstruct the 7.01 landslide three-dimensional geological model in Lihua Township,Dafang county,and uses the Static Strategy module of the finite element software ANSYS Workbench.The self-weight conditions,the stress and strain distribution iso-lines of geotechnical soils before landslide were simulated respectively.The results show that the stress is con-centrated in the middle and rear parts of the landslide,and it is in a long strip distribution.It is basically in line with the deformation of the landform before and after the landslide.This proves the validity and feasibility of the simulation model,and judges that the slope is started from the middle and back parts.Sliding,moving the middle and lower rock and soil bodies,A gradual landslide is formed along the straight layer of limestone.This simulation analysis provides reference for identifying similar geological hazards and judging their failure patterns in the future,and is helpful for guiding the prevention and control of similar Geological hazards.
