摘要
Aiming at 14 typical landslides in Xiluodu reservoir area, 8 key indexes, including average surface slope angle, cutting degree of the gullies on landslide bodies, closing condition of bottom land (or drainage conditions), the average inclination of sliding surface, shape of sliding surface, the ratio of length of downslide section and total length of sliding surface, sliding body structure and recent deformation and failure signs, was preferentially gained by using grey relation analysis method, based on preliminarily presented discrimination indexes for potential landslides in that area. Then, by using distance discrimination analysis,the discrimination model for potential landslides in Xiluodu reservoir area was built. The results show that prediction accuracy rate of the method is as high as 100%.
