摘要： 将基于强度折减法的黏土边坡稳定模拟计算与理论方法计算进行对比分析，希望找到一个更好的计算方法来提前预知以及预防因边坡失稳导致的灾害。首先采用Abaqus软件进行模型构建以及计算分析，然后采用瑞典条分法以及毕肖普条分法分别对所构建的模型进行计算。通过对比分析基于强度折减法的数值模拟计算与两种理论方法计算得出的结果，发现强度折减法的结果与两种理论方法的结果都比较接近，但是与瑞典条分法得出的结果更加吻合。基于强度折减法的数值模拟计算不需要提前假定滑动面的位置来进行计算，就能直接得到边坡的稳定安全系数，并且计算更加方便快捷，还能得到土坡各个点在不同时期的位移、应力以及塑性区等。

Abstract: There are many natural hazards caused by the slope instability, in this paper, the stability simulation of a clayey slope using the strength reduction method is compared with the theoretical method. A better way to predict and to prevent hazards caused by the slope instability in advance are obtained through the numerical analysis. In this paper, the numerical simulation software ABAQUS is used to establish the prediction model. Then, the theoretical method includes Sweden slice method and the Bishop’s slice method are used to evaluate the model. Through the comparative analysis, the results of ABAQUS numerical simulation software are very close to the theoretical methods, but the numerical simulation is more convenient and fast, and the stability and the safety factor of the slope can be obtained directly without assuming the position of the sliding surface in advance, and the displacement, stress and plastic zone of each point of slope at different times can be obtained.

Key words: Strength Reduction, Sweden Slice Method, Bishop’s Slice method, Slope Stability
