| Abstract: | The strength reduction method is used for the analysis of two-dimensional and three-dimension slope stabilities, whose results are compared with the result of limit equilibrium method, the result shows the strength reduction method is feasible. The factors influencing slope stability are studied, and it is analyzed the safety factor of a three-dimensional slope with same surface load, yet a different active area. It is also pointed out that slope stability has three-dimensional effect, which has some guidance for analyzing the stability of a slope. |
