The Genesis Mechanism Analysis of Qinglong Landslide in the Central Region of Yunnan Province Water Source Diversion Reservoir Area of the Jinsha River

Qinglong landslide is a very typical landslide in the central region of Yunnan Province water source diversion reservoir area of the Jinsha River. The geological background of the landslide region is introduced,including Landform, stratum lithology and geological structure and hydrogeological condition. Based on the collected geological data and according to the results of site investigation, the complete picture of Qinglong landslide is provided. Then the image of 3d vision is made. The longitudinal profile and cross-sectional profile are drawn. At last, The genesis mechanism of Qinglong landslide is analyzed from the point of landform, Rock mass structure and Geological structure. The study is helpful to understand the status of other landslides and can provide the basis of appraisal of reservoir bank stability.
