Abstract: Limit equilibrium method is a major analytical tool for the slope stability projects. Recently, an innovative approach to the slope stability problems, which is called progressive failure analysis method, has been proposed. This paper presents the comparative evaluations of Xiangjiapo Landslide by using the conventional and new methods. The conventional method could only describe the earlier portion of slope instability but the new method could characterize the entire progressive failure of a landslide. The results conclude that both the conventional and the new method can be used in the engineering practice and the new method has the advantage of characterizing the entire progressive failure of a landslide.

Key words: Slope Stability, Progressive Failure, Stability Analysis, Evaluation of Stability Factor
