【摘要】 针对窑街矿区“9·4”大规模山体滑坡,从实际工程地质条件出发,综合考虑了自然和人为影响因素,采用数值分析方法分别对自然状态下的边坡、遭遇强降雨后的边坡、受到民采扰动的边坡以及民采后又遭遇强降雨时的边坡四种情形下影响边坡稳定性的关键因素进行了层次分析。研究表明:小窑采动是导致大规模山体滑坡的主要因素,边坡遭遇降雨是导致山体滑坡的诱导因素。更多还原

【Abstract】 Aimed at the large-scale land sliding occurred on September 4th, 2005 in Yaojie coal field, the presented work proceeds from geological conditions and takes several natural and humanity factors into account. It carries out numerical simulation according to four different conditions which contain natural slope, slope after the rainfall, slope disturbed by small-scale mining as well as slope affected by both rainfall and small-scale mining. The purpose of it is to find out the pivotal influencing factor and reveal the failure mechanism. The research shows that small-scale mining is the major influencing factor of this land sliding and rainfall is the induced factor.更多还原
