Description :
A three-dimensional multi-planar sliding surface method developed from the two-dimensional method is proposed to identify the shape and/or volume of a shallow failure that appears on a mountain slope during heavy rainfall. It was applied to a digital elevation model to determine the site and form of a critical sliding mass on a mountain slope. The method was applied to an actual mountain slope on which a shallow failure caused by heavy rainfall took place. The most probable unstable mass calculated by the model was almost the same as that at the failed site.
