以一均质土坡为例，分别采用瑞典法、毕肖普法、简布法等极限平衡法以及有限元强度折减法计算该土坡的稳定性。研究了土条数目对条分法、网格密度对强度折减法的影响；并对这几种土坡稳定性分析方法的计算结果进行了对比分析，结果表明：极限平衡法和有限元强度折减法两类方法计算得到的安全系数和滑动面基本一致，极限平衡法得到的安全系数偏安全；各方法计算的模型划分得越精细，得到的安全系数越小，但随着精细程度的增加，安全系数减小的趋势趋缓。

This study takes a type of homogeneous soil slope as example, adopts the Fellenius method, the Bishop method, the Janbu method, and the finite element strength reduction method respectively to calculate the stability of the dirt slope, and then analyses the effects of the number of soil stripes on the slice method and the effects of the grid density on the strength reduction method. In addition, it makes a comparison of the calculation results of these methods for slope stability analysis. The results show that the safety factor and the slip surface of the limit equilibrium method and finite element strength subtraction method were basically the same, and the safety factor of the limit equilibrium method was stronger than that of the finite element strength reduction method; the finer the model partitioning is, the lesser the safety factor becomes; but with the increase of the partitioning density, the safety factor decrease trend levels off.
