针对山东莱州三山岛露天金矿矿坑高陡岩质边坡稳定性的问题，综合考虑库水位

针对山东莱州三山岛露天金矿矿坑高陡岩质边坡稳定性的问题，综合考虑库水位对边坡的水压力、暂态渗流力场、应力场，改进岩质边坡稳定性计算理论；选取边坡487勘探面，运用改进理论结合有限有限元法计算边坡在水平方向上的位移值，对比运用深孔测斜仪测量的数据，验证该理论的实用性，同时分析降雨在岩质边坡入渗的过程，研究边坡瞬态安全系数随时间变化关系。研究结果表明：边坡在水平方向的理论计算位移值与深孔测斜仪测量值进行对比，发现计算值与实测值基本一致，最大误差为0.02mm，说明该理论对渗流状态下边坡稳定性分析具有良好的实用性；降雨条件下边坡瞬态安全系数随时间的变化曲线呈“V”形，降雨后的安全系数对比与降雨前减少了10.12%；强降雨入渗引起了地下水位的上升，边坡安全系数最低时，暂态饱和区集中在边坡临空面的5-30m的范围内。
