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,最可能的破坏方式为从上向下扩展
Based on the study of the spatial variability of rock mass properties, the reliability of the working slope of northern open pit mine in Yima Mining Bureau was systematically studied by FLAC numerical simulation, physical simulation test and Monte-Carlo-Sarma method. At the same time, The possible failure modes of formation are analyzed by reliability analysis. The results show that the failure probability of slope is acceptable, and the most likely failure mode is from top to bottom
