【 摘 要 】

This paper presents results of comparative slope stability analyses conducted by limit equilibrium and strength reduction methods. Several slopes, taken either from geotechnical practice or literature review, are considered. The influence of tension, distributed load, finite element size, model parameters on the location, shape of the critical failure surface, and the corresponding value of the factor of safety, are all analysed. Both methods provide similar results if they are correctly applied using appropriate software programs.
