Study On The Stability Evaluation And Control Scheme Of Reservoir Landslide At Yinghu Lake

In large water conservancy and hydropower engineering, because of the reservoir and the influence of many factors, landslide hazard is particularly serious, every year, the economic losses caused by the landslide is very huge. reasonable analysis of landslide stability is an important issue to solve the problems of the successful implementation of large hydropower projects.The Yaotoucun landside is located in the Hanbin District southwest of Ankang City, belonging to the shallow surface soil landslide. The deformation and failure of the landside have occurred many times since 2001, threaten the life and property safety of the residents around the slope and the ecological environment of Yinghu lake. The landslide is connected with the Yinghu Lake, the groundwater in front of the slope is supplied by the Yinghu Lake and changes over the water level of the lake. In the rainfall season, under the influence of reservoir water level change and rainfall, the slope is easy to cause landslide. The research object of this thesis is to analyze the geological environment background, scale shape of landslide and characteristics of rock and soil mass of the Yaotoucun landside on the basis of fully collecting data and laboratory test. In order to more intuitively understand the occurrence process and movement pattern of landslide, the MADIS GTS NX software is used to simulate the slope, and the stability of slope is analyzed by the method of qualitative and quantitative analysis, speculate on the future development trend of the landslide. Finally, according to the scale of the landslide, the situation of the stability and the trend of the deformation, put forward some programme of landslide prevention.
