Research of Formation Mechanism for the III# Landslide on a Hydropower Station Reservoir in Yellow River

Toppling-deformation tends to occur in the anti-dip bedded slope, but recently we find that the steep bedding rock slope also exists this mode. The study of the formation mechanism has an important significance to the evaluation of the slope stability. This paper takes the III# landslide which is in front of a dam in Yellow River as an example. Based on the engineering geological survey, the failure process of the landslide is studied by qualitative analysis and numerical modeling. The results indicate that the failure process of the landslide includes rock mass unloading, toppling deformation and sliding. The results of using finite element match to that of discrete element calculation, which proves the rationality of the conclusion.
