- Abstract
This paper deals with the full dynamic process of landslides, including the landslide initiation process and the mass movement and accumulation process. This paper presents a new approach combination of the limit analysis and the depth-averaged Savage-Hutter model to simulate the full dynamic process of the landslides triggered by earthquakes. In this procedure, limit analysis is used to find the critical sliding surface. Subsequently, the depth-averaged Savage-Hutter model is used to simulate the mass movement and accumulation based on the critical sliding surface. This approach is illustrated by simulating the full dynamic process of a landslide triggered by earthquake. Simulation results indicate that the position of the sliding surface has a strong effect on the mass movement and accumulation. Finally, results from the simulation of the Daguangbao landslide and the real-world effects of the landslide are compared. The results indicate that the proposed approach is valid and reasonable to predict the full dynamic process of landslides.
