Abstract
This paper presents a new theory of 3D limit equilibrium based on the 3D geological model built by Petrel.On the assumption that centers of gravity of the blocks are in a straight line and consistent with the main sliding direction.The sliding surface area
landslide volume and center of gravity sliding cutting angle are determined by the model.The stability analysis method of soil slope is established through ignoring the vertical shear between the blocks.This method is simple and practical
