Abstract:

Existing limit-equilibrium stability analysis methods are two-dimensional; a few methods for correcting or extending a two-dimensional analysis have been proposed. Presented in this paper is a general method for three-dimensional limit-equilibrium stability analysis. Limiting cases are considered in order to study preliminary implications of three-dimensional stability analyses. The method lends itself to both hand calculation and computer application. Method can also be used together with finite element analysis which should make it possible to set up a fairly realistic model for soil and slope behavior.
