The Stability Analysis And Control Methods Of Gaozhi Pond Dam Landslide

China is one of the most serious areas of landslides disaster, the country has more than 10000 villages by landslides disaster. May 12, 2008 Wenchuan Sichuan County, 8.0 earthquake, the focal depth, high intensity, so that the earthquake occurred in a certain range of landslides, landslides and other geological disasters. Based on the investigation and evaluation of the landslide in Deyang city in Sichuan Province, the paper can be used as a reference for the work of the base and the reference to reduce the risk and damage of the disaster.Based on the investigation of the geological environment condition of the dam landslide, the paper discusses the form of the landslide, the sliding body, the slide zone and the sliding bed, and analyzes the characteristics, stability, influence factors and deformation mechanism of the landslide deformation. Pond dam landslide is along the bedrock sliding surface of soil slope, slope direction and rock tendency is consistent, the longitudinal surface is folded. The landslide is stable in natural state, and in the condition of heavy rain, the landslide is in stable state. Under the condition of earthquake, the basic steady state.According to the characteristics of landslide hazard in weir dam, the line control measures are put forward to prevent and control the drainage ditch, and provide a reference for the similar landslide prevention and control.
