The feasibility study of strength-reduction method with FEM for calculating safety factors of soil slope stability

ZHANG Lu yu 1, ZHENG Ying ren 1, ZHAO Shang yi 1, SHI Wei ming 1 (1 Logistical Engineering University, Chongqing 400041,China)  
The shear strength reduction method(SRM) with FEM on analysis of slope stability is increasingly applied. All round analyses were made for the influence on computation precision caused by different soil yield criterions, FEM accuracy, slope height, cohesion and friction angle. Measures to improve the precision were put forward. Computation and comparison were made for 106 cases. The results show that the safety factors calculated with SRM were averagely exceeding those with Bishop simplified method at 5 7% and the scatter was small. The proposed measures for improving precision in valid and the method of FEM-SRM to analyzing slope stability can be applied.
