BLOCK THEORY METHOD FOR DETERMINATION OF SLOPE SLIP SURFACE AND ITS STABILITY ANALYSIS

Generally speaking,a complex slope is composed of different kinds of rocks and the stability is controlled by the rock structure and graduall formation of slope slip surface. Based on these characteristics, in this paper a block theory method is suggested for determination of slope slip surface and analysis of the stability of a large slope engineering by Sarma equilibrium method and other slip surface shape, the results verfied the block theory method.
