摘　　要：采用压坡体的坝体加固方式并对压坡体进行修整,可有效改善尾矿库的坝体稳定性。以某尾矿库主坝为例,为解决其稳定性问题,基于该尾矿库的特殊性,采用修整压坡体的方式对坝体进行加固处理;结合数值模拟、方案比选的方式,对主坝整体边坡压坡前后及修整前后的坝体稳定性进行对比分析。结果表明:经压坡体压坡后,尾矿库主坝稳定性得到显著提升;减少工程量的修整方案对尾矿坝整体边坡抗滑稳定安全系数影响较小。The stability of the tailings dam can be effectively improved by adopting the reinforcement method of the pressing slope body and repairing it.Taking the main dam of a tailings reservoir as an exam⁃ple,in order to solve its stability problem,based on the particularity of the tailings reservoir,the dam body is reinforced by repairing the pressingslope body.Combined with numerical simulation and scheme compari⁃son,the stability of the whole slope of the main dam before and after the pressure slope and before and after the repair is compared and analyzed.The results show that the stability of the main dam of the tailings reser⁃voir is significantly improved after pressure slope.The repair scheme of reducing engineering quantity has lit⁃tle influence on the safety factor of anti-sliding stability of the whole slope of tailings dam.
