A Three-dimensional Multi-planar Sliding Surface Method to Predict an Area of Surface Failure

Abstract

A three-dimensional multi-planar sliding surface method is proposed in this paper to predict an area of surface failure which appeared during a heavy rainfall. The safety factors calculatoed by the method show similar to those obtained by different methods (Hovland and simplified Janbu). A dangerous area is predicted by an application of the method to a digital land form model.
