摘　　要：在Morgenstern-Price法及Sarma法理论假设的基础上,通过对岩质—土质混合边坡岩土分界面受力的推导,并假设不平衡力矩Mc,结合水平地震作用系数kc,建立了岩质—土质混合边坡稳定性的迭代求解方法;同时,通过对岩质—土质混合边坡算例的计算分析,验证了上述方法的合理性及可靠性,从而为岩质—土质混合边坡稳定性计算的理论研究提供了一种新的思路。On the base of Morgenstern-Price method and Sarma method, a method of iterative solution is deduced combined with Horizontal seismic coefficient Kc, to calculate the stability of soil-rock slope on the assumption that unbalanced moment Me is set. Meanwhile, through the calculations and the analysis of soil-rock slope examples, the rationality and reliability of the method above is verified. With this study, a new theory of the stability calculation of the soil-rock slope is proposed.
