摘要: 为了研究外界因素对结构面控制型边坡稳定性的影响,以兰尖铁矿营盘山段边坡为工程背景,采用Geo-Slop软件,分别分析了该边坡在地下水、地震载荷以及地下水和地震载荷共同作用下的边坡稳定性,结果表明:地下水对边坡稳定性影响较小,安全系数的变化范围在0.015~0.030;地震载荷对边坡稳定性的影响较大,安全系数的变化范围在0.125~0.165;在地下水和地震载荷共同作用时,整个边坡处于临稳状态。

Abstract: To study the effect of external factors on the surface-controlled slope stability,this paper takes the slope of Yingpanshan section of Lanqian iron mine as engineering background,and adopts the Geo-Slop software to analyze the slope stability in groundwater,seismic loads and the interaction of underground water and seismic loads respectively. The results showed that: groundwater has less impact on slope stability with safety coefficient ranging between 0.015 and 0.030;Seismic load has greater impact on slope stability,and its safety coefficient varies between 0.125 and 0.165. Under the interaction of groundwater and seismic loads,the entire slope lies in a critical stable state.
