摘　　要：为了解决伊敏露天矿生产调节蓄水池坝体边坡的渗流及稳定性问题,基于现场实际调查,采用数值模方法研究得出坝体内部的孔隙水压力变化趋势、渗流量、渗流路径等重要数据,并将这些数据代入边坡稳定安全系数的计算中。结果表明:在渗流场和应力场耦合作用下,水位抬升会造成坝体边坡的稳定性下降,并基于此结论提出了防治建议。In order to solve the seepage and stability of production regulated reservoir dam slope, based on field investigation and survey,the article uses numerical simulation method to studythe pore water pressure change trend, seepage flow and seepage path,and brings data into the calculation of safety factor of slope stability.The results show that under the coupling action of seepage field and stress field, the water head rising will cause the slope stability to decline. The article puts forwardprevention and control suggestions.
