Abstract：
In this paper, based on field investigation data, using statistical analysis, stress analysis and numerical simulation method, results show that the quaternary clay, permian schist and amphibolite are easy to slide. And the linear model and convex slope are more prone to landslide and collapse in the linear model, convex slope, depressed tubulovillous adenoma and ladder types. And the height and gradient has obvious effect on the landslide, the landslide slope mainly occurs in 20°~50°with 10 to 30 m height. Landslides are widely distributed in all directions, but the landslide in directions 45°~135°and 180°~270°slope are dominant. The probability of sunny slope landslide is higher than in south faced slope. Slope collapse mainly occurred in the slopes with more than 45° gradient and the height with less than 30 m.
