Abstract

This paper pertains to the application of optimization technique in the stability analysis of creeping slopes reinforced with passive piles. A method of stability analysis of the pile-reinforced slopes has been derived by extending the friction circle method of slope stability analysis in conjunction with the pile stability analysis proposed by Ito and Matsui. The problem has been cast into a mathematical programming. The solutions have been isolated by formulating the problem as one of non-linear programming. The applicability of the developed method has been verified by comparing the predicted failure surfaces with those results, reported in literature.
