ABSTRACT

Slope stability analysis is performed either by limit equilibrium methods or by finite element methods. The limit equilibrium methods are widely used in design practice and have proven to be a successful method for the assessment of the stability of the slope. Numerical comparisons have shown that the finite element method is a reliable method for assessing the safety factor of slope and corresponding critical slip surface. The chapter presents how the load transfer mechanism of the ground anchor affects on the stability analysis of anchored slope. It discusses the load transfer distribution was incorporated into the limit equilibrium stability analysis of the anchored slope and the results were compared with the results of finite element analysis. The limit equilibrium analysis of the anchored slope is quite open used in design practice due to the easiness of the analysis. Slope failure and numerical non-convergence occur at the same time, and are accompanied by an increase in the displacements.
