Abstract
This paper describes recent advances in geotechnical stability analysis that combine limit equilibrium analysis with finite element stress analysis to provide a factor of safety and the failure load. This method, known as the finite element limit equilibrium method, is used to propose and prove the necessary and sufficient conditions required for determining the limit equilibrium state for a slip surface of soil. Based on the limit equilibrium conditions along a slip surface, the method could be used to perform a slope stability analysis and to evaluate failure loading in rigid footings and retaining walls. After a brief outline of the methods, several representative two-dimensional examples are analyzed.
