【 摘 要 】

Large scale landslide accumulations are often seen in the construction of hydropower stations in Southwest of China. It is of great engineering significance to study the development process of these landslide accumulations and their development stages. In this paper, a landslide accumulation of a hydropower station is taken as the object of study. Through the three-dimensional discrete element analysis software 3DEC, the development process of the accumulation body is divided into five stages, and the deformation and failure characteristics of each stage are analyzed in detail. The research of this paper is of great help to guide the safety operation of the project.
