Abstract: Several widely used analytical methods for slope stability that were derived from the ultimate equilibrium theory are compared in this paper. Their applicable range and accuracy have been discussed respectively and verified with three practical examples. It is concluded from the results of analyses that:the result from linear slip surface method is a bit high; on the contrary Sweden circular slice method is a bit conservative; the simplified Bishop method can be used effectively in evaluating slope stability.

摘要： 将目前运用得较为广泛的极限平衡法中几种边坡稳定性计算方法进行了对比分析.研究其各自的适用条件、计算精度,通过对3个算例稳定系数进行比较,得出结论:直线滑动面法计算的稳定性系数偏于不安全,而瑞典条分法偏于安全,简化的毕肖普法计算的结果则比较接近实际.
