针对三山岛露天坑尾矿库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，运用改进理论结合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数据，发现计算值与实测值基本一致，最大误差为0.02mm，验证了该理论对渗流状态下边坡稳定性分析具有良好的实用性；降雨条件下边坡暂态安全系数随时间的变化曲线呈“V”形，降雨后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。

For Sanshan Island open pit tailings library high steep rock quality slope stability of problem, integrated consider library level on slope of water pressure, and temporarily State seepage field, and stress field, improved rock quality slope stability calculation theory, using improved theory combined limited Yuan method calculation slope in level direction Shang of displacement value, compared using deep hole measuring oblique instrument measurement data, found calculation value and measured value basic consistent, Maximum errors for 0.02mm, validation has the theory on seepage State Xia slope stability analysis has good of practical; rainfall conditions Xia slope temporarily State safety at any time between of changes curve is "v" shaped, rainfall Hou safety compared and rainfall Qian reduced has 10.12%; strong rainfall into infiltration caused has groundwater bit of rose, slope safety minimum Shi, temporarily State saturated district concentrated in slope Pro empty surface of 5-30m of range within.

Sanshandao pit for the problem of high steep rock slope stability of tailings, considering the water level of water pressure slope, transient seepage force field, stress field, improvement of rock slope stability calculation theory, the use of improved theory with finite element method of slope displacement in the horizontal direction, compared to the use of deep inclinometer measurements, that the calculated and measured values ​​are basically the same, the maximum error is 0.02mm, verify the status of the theory of seepage below slope stability analysis has good usability; transient slope under rainfall conditions for safe coefficient with time curve showed a "V" shape, after rain rainfall safety factor compared with the former decreased 10.12%; heavy rainfall caused the water table infiltration the rise, the minimum safety factor of slope, the transient saturated zone concentrated in the range of 5-30m slope free face.
