A Simple Method for Evaluating Progressive Failure Process of Rainfall-Induced Shallow Landslide
Rainfall-induced shallow landslide is a significant issue in the south and southwest of China. It generally exhibits the behavior of progressive failure. However, the overall stability of coefficients can’t reflect the development of the local failure. In this article, a simple method, which is utilizing the progressive failure combined with the improved Green-Ampt model, is proposed to solve this problem during the rainfall. Taking the Guzhang shallow landslide as an example, it shows that the initial failure area of the shallow landslide is revealed in the front and middle of the landslide during the rainfall.
