In this paper, the slope with horizontal weak interlayer is taken as the research object, and the safety factor and the location of the failure surface of the slope are calculated by finite element strength reduction method and limit equilibrium method respectively. The results show that when the slope is mixed with soft layer, the positions of the critical failure surfaces calculated by the two methods are quite different, but their safety factors are relatively small. Which method is more accurate needs to be analyzed in combination with the specific conditions of the slope. Through comparative analysis, the calculation efficiency of limit equilibrium method is much higher than that of strength reduction method. The results of this paper provide reliable reference for engineering analysis.
