摘要

Based on investigation of engineering geological conditions, this paper examines the slide plane feature and location of a large scale landslide on a highway. It analyzes the development process and stability status of the landslide. According to the borehole data, the rock mass and sliding surface parameters are obtained. Combining with inverse computation of parameters,the sliding surface’s c and φ values are obtained. Finally under the condition of abnormal（rainstorm） condition, the safety factor of the landslide is found to be 0.91. The value shows that when facing with a long heavy rain,the landslide can be further developed.
