尾矿坝边坡地质勘查及稳定性研究

Geological exploration and research of tailings dam slope stability

以某尾矿库为研究对象,通过地质勘察,探讨了边坡水文地质条件及土体物理力学参数,并基于强度折减法对尾矿坝边坡进行数值模拟,结果表明:该尾矿坝边坡没有滑坡及泥石流等灾害发生的条件,库区工程地质条件相对较好,水文地质条件简单,在暴雨状态下边坡的稳定性有明显降低。

Taking the tailings as the research object,through the geological investigation to determine the slope hydrogeology and soil physical and mechanical parameters,and based on strength subtraction for numerical simulation of tailings dam slope. Results show that： there is no largescale collapse,landslide,debris flow and other geological disaster conditions,reservoir engineering geological conditions are relatively good,simple hydrogeological conditions,state of the slope stability is significantly reduced.
