| 摘 要： | 不平衡推力法是工程上常用的一种边坡稳定性分析方法。为研究不平衡推力法中条间推力倾角变化对边坡稳定性的影响，假定了条间推力倾角角度系数μ，并令其在0到1之间取值，然后推导出修正后的不平衡推力法安全系数计算公式。通过两个边坡算例的分析，探讨了条间推力倾角角度系数μ的变化影响规律，并指出在实际工程中，通过改变μ的取值可在不平衡推力法中获得与实际情况比较相符的条间力方向。

| Abstract: | Unbalanced thrust force method is a method commonly used to analyze slope stability. In order to study how change of inter-slice thrust force inclination affects slope stability, it is assumed that the angle coefficient μ of the inclination is instructed to be 0～1, and then the formula calculating safety factor for amended unbalanced thrust force method is deduced. Through analysis of two cases, the laws of angle coefficient μ change is discussed and, in practical engineering, it is pointed out that with change of μ value, the direction of inter-slice force relatively consistent with actual situation may be obtained when unbalanced thrust force method is used. |
