摘要： 采用节点虚流量法，对凹山采坑改建尾矿坑西北帮边坡地下水渗流进行计算；结合凹山采坑内水位的变化及长期被浸没岩体的软化作用，依据极限平衡法理论，探讨凹山采坑西北帮边坡的稳定性。结果表明，相对边坡高度，水位骤升不超过1.7 m，水位骤降不超过0.5 m时，长期被浸没岩体的边坡稳定性变化不大；但是岩体软化作用会使边坡稳定性有所降低。研究结果对类似边坡有一定的参考价值。

Abstract: The node virtual flow method is used to calculate the groundwater seepage on the northwest side slope of the tailing pit reconstructed from the Aoshan pit;According to the limit equilibrium method,considering the change of water level in the pit and the softening phenomenon of longterm submerged rock mass,the stability of the slope on the northwest side of the pit is discussed.The results show that when the water level rises no more than 1.7 m and the water level falls no more than 0.5 m,the slope stability of the longterm submerged rock mass does not change much;However,the softening of the rock mass will reduce the longterm stability of the slope.The research results have certain reference value for similar slopes.

Key words: ground water seepage, change of water level, softening effect, slope stability
