End Effects on Stability of Cohesive Slopes

This paper discusses stability analysis of cohesive slopes with finite length. The method of analysis is based on limit equilibrium techniques and variational calculus. The three-dimensional stability factors are calculated as the functions of the ratio of failure length to slope height and slope angle. Based on these calculations three-dimensional stability charts are presented. And a method of inverse calculation of cohesion c on a three-dimensional slip surface is proposed.
