义马北露天煤矿工作帮边坡可靠性研究

The reliability research on the working slope of North Surface Coal Mine of Yima Coal Administration

基于岩体性质空间变异性研究,运用FLAC数值计算、物理模拟试验、Monte-Carlo-Sarma法等对义马矿务局北露天煤矿工作帮边坡进行了系统的可靠性研究,同时对边坡可能形成的渐进破坏方式进行了可靠性分析,研究结果表明,边坡的破坏概率是可以接受的。

Based on the spatial variability of rock mass strength, a reliability analysis on the working slope of North Surface Coal Mine of Yima Coal Administration is systematically performed by means of FLAC numerical software, physical simulation experiment and Monte-Carlo-Sarma technique. At the same time, a probable progressive failure mechanism is studied by reliability method. The failure probability of the slope can be accepted according to the engineering function.
