摘要
Suffering the influence of the Three Gorges Reservoir impounding, Nierwan landslide already has produced very big transmutation, threatening the security of people’s life and property. This paper introduces the characteristics of geology, structure and deformation of the landslide. On the basis of the study mentioned above, the formation mechanism and influencing factors of the landslide are deeply analyzed. Finally this paper adopts transfer coefficient method to calculate and evaluate the stability. According to study, the landslide is in the status of creeping or failure. So Nierwan Landslide needs to be controllacl.
