ABSTRACT
The recently developing finite element strength reduction method can give full consideration to the pile-soil common function. Through the strength reduction the internal force of structure (Zhen et al. 2004, 2005, 2009; Xu et al. 2010; Yang et al. 2010) can be calculated. As compared with the traditional limit equilibrium method, the finite element strength reduction method is used not only for accurately calculating the safety coefficient and the critical slip surface, and can be for reproducing the development process of rock mass deformation, especially in the retaining structure design, the advantages are more obvious. The calculation of Wulong county large landslide and large geological mechanical model test results and centrifugal model test results also proved the applicability of finite element strength reduction method (Zhao et al. 2009; Xu et al. 2009, 2010).
