EVALUATION AND ANALYSIS OF SLOPE STABILITY OF GRAVEL SOIL STEEP SLOPE IN MULTI-FAULT FOLD OVERLAPPING AREA
In this paper,based on the investigation and geotechnical test of the fracture zone of steep slope of gravel soil in a multi-fault fold superposition area of Yunnan-Guizhou Plateau,the main geotechnical parameters of gravel soil,sliding surface and bedrock in the landslide area are obtained.The inverse algorithm is used to test the shear strength index of landslide,and the landslide shape characteristics,deformation and failure mode and the formation mechanism of landslide are defined.Finally,by calculating the characteristic stability coefficient and characteristic residual thrust of different characteristic sliding faces,the stability and risk of landslide are analyzed and evaluated,and the construction suggestions are given.
