为解决常规的体系可靠度方法难以计算具有众多失效模式的复杂边坡稳定可靠度的问题,研究基于矩阵的体系可靠度法(MSR法)分析边坡体系的方法;结合多尺度法,把边坡体系拆分为多个并行子体系,每个并行子体系作为体系的一个"超构件",以达到减少优化变量个数、降低系数矩阵规模的目的.对矿山边坡体系进行实例分析.研究结果表明: MSR法能获得比常规界限法更加精确的计算结果;将MSR法与多尺度法相结合,可解决失效模式较多的复杂边坡体系可靠度的计算问题,扩大MSR法的应用体系范围;MSR法使边坡的体系失效概率估计区间稍增大,但计算量呈指数级减少,且可利用现有优化软件进行矩阵运算和优化计算,便于实现边...

In order to solve the problem that general system reliability methods can hardly be applied to calculate the stable reliability of complex slopes with multiple failure modes, the matrix-based system reliability method (MSR method) was studied. With multi-scale method, the slope system was decomposed into many parallel sub-systems which were regarded as " super-components" so as to decrease optimal variables and reduce the scale of matrixes. A project case of a mine slope system was analyzed. The results show that the results by the MSR method are more accurate than that by general system relia...
