摘　　要：针对复杂边坡结构,将多个参数考虑成随机变量,利用矩阵理论推导了结构安全系数K和可靠指标β的矩阵通用计算公式,以及均质边坡结构对应的特例公式.结果表明,这些公式反映边坡稳定性的规律性,可为有限层边坡结构可靠性分析方法在实际工程中的推广使用提供方便,并为其模块化编程提供了理论依据.In the case of complex multilayer slope structure, by use of matrix theory and with a number of parameters considered as random variables ,general matrix expressions are given to safety factor K and reliability index β. Relevant expressions are also given to monolayer slope structure. Results show that these expressions make known the regularity of stability of slope structure with several layers, and help extend the application of the slope structure reliability analysis to practical engineering. Furthermore,theoretical basis is provided for compiling the modulization program of the analysis.
