STABILITY ANALYSIS FOR SLOPES WITH ARBITRARILY-SHAPED GEOMETRY AND SLIDING SURFACE

Keizō Ugai, Kenji HOSOBORI

Open full text 4 citations

Abstract

In order to analyze 3-D (three-dimensional) slope stability, a new 3-D slice method is proposed by extending 2-D Spencer's method. This method is applicable to the case of non-circular slip surface and satisfies moment equilibrium and vertical and horizontal force equilibrium for sliding mass. Two examples of calculation are presented to show the accuracy of the method and comparatively large 3-D effect in a practical case.
