| 摘 要： | 从剩余推力法和简布法基本原理出发．分析了两种计算方法的不同假设条件，并结合实例，对滑坡稳定性进行了计算，最后对两种计算结果进行了分析与比较，得出了剩余推力法计算的稳定性系数总是比简布法计算的要偏大、用剩余推力法计算稳定性时水的影响比地震要稍大以及用简布法计算稳定性时水的影响比地震要稍小的结论。

| Abstract: | In terms of basic principles of Residual Thrust Method and Janbu Method,this paper analyzes the assumption conditions of both methods and takes the calculation of landslide stability.The results from both methods are analyzed and compared. The conclusions indicate that the stability factors from Residual Thrust Method are larger than those from Janbu Method, and that the influence of water level on stability factor is a little greater than that from earthquake when Residual Thrust Method is used to calculate stability factor of landslide, while the influence of water level on stability factor is a little smaller than that from earthquake when Janbu Mmethod is used to calculate stability factor of landslide. |
