摘要：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。

Summary: for Shandong laizhou Sanshan Island Open gold pit 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; selected slope 487 exploration surface, using improved theory combined limited limited Yuan method calculation slope in level direction Shang of displacement value, compared using deep hole measuring oblique instrument measurement of data, validation the theory of practical, while analysis rainfall in rock quality slope into infiltration of process, Study on transient safety factor of slope changes over time. Research results showed that: slope in level direction of theory calculation displacement value and deep hole measuring oblique instrument measurement value for compared, found calculation value and measured value basic consistent, maximum errors for 0.02mm, description the theory on seepage State Xia slope stability analysis has good of practical; rainfall conditions Xia slope instant State safety at any time between of changes curve is "v" shaped, rainfall Hou of safety compared and rainfall Qian reduced has 10.12%; strong rainfall into infiltration caused has groundwater bit of rose, slope safety minimum Shi, Transient saturation are concentrated in the context of free surface of slope 5-30m.

Abstract: Shandong Laizhou Sanshan Island open pit gold mine pit problem of high steep rock slope stability, considering the water level of water pressure slope, transient seepage force field, stress field, improved rock slope stability calculation theory; select 487 slope surface exploration, the use of improved theoretical slope displacement in the horizontal direction of the finite element method, using deep contrast inclinometer measurement data to verify the usefulness of the theory, and analyzes rainfall rock slope infiltration process, study the transient slope safety factor changing with time. The results show that: in the theoretical slope displacement values ​​and deep inclinometer measurements in the horizontal direction are compared, that the calculated and measured values ​​are basically the same, the maximum error is 0.02mm, described the state of the slope stability of the seepage under the theory analysis has good usability; transient safety factor of slope under rainfall conditions over time curve showed a "V" shape, the safety factor after rain reduced rainfall in comparison with the previous 10.12%; heavy rainfall infiltration caused a rise in the groundwater level , a minimum safety factor of slope, the transient saturated zone concentrated in the range of 5-30m slope free face.

Abstract: according to the Shandong Laizhou Sanshandao gold mine pit of high steep rock slope stability problem, considering the water level on the slope of the water pressure, transient seepage field, stress field, the calculation theory of improving the stability of rock slope; slope selection 487 exploration, using the improved displacement theory combined with the calculation of slope in horizontal direction the limited value of the finite element method, compared by the deep hole inclinometer measuring data, verify the practicality of the theory, and analysis of rock slope in rainfall infiltration process, the relationship between the safety factor of slope transient changes with time. The research results show that the theoretical calculation of slope in horizontal displacement and deep hole inclinometer measurements were compared, found that the calculated value is consistent with the measured values, the maximum error is 0.02mm, this method has good practicability on the seepage state of slope stability analysis; curve slope transient safety factor under the condition of rainfall over time a "V" shape, compared with the safety coefficient of rainfall after rainfall has decreased by 10.12%; rainfall infiltration caused the rise of ground water level, the minimum safety coefficient of slope, transient saturated zone is concentrated in the range of free face of the slope in 5-30m.
