摘　　要：把边坡稳定性分析的剩余推力法与可靠度分析的统计矩法相结合,建立了滑坡推力的概率分布模型,确定了滑坡推力与允许失效概率之间的定量关系,并对一边坡进行了实例分析。结果表明,文中计算方法与传统定值分析法得到的结果具有较好一致性,是可行和有效的。Combined with residual thrust method for slope stability analysis and statistical moment method for liability analysis, this paper establishes probability distribution model of slope thrust; determines the quantitative relation between slope thrust and permissible failure probability and carries out analysis on an actual slope. It is indicated that the result from the said calculation method in this paper is in conformance with that from traditional fixed value analysis method, which is feasible and effective.
