摘　　要：针对绥中小盘岭尾矿库溃坝原因,提出具体治理方案。治理方案包括原尾矿初期坝补坡加固、原尾矿库疏干及防洪、原尾矿堆积坝削坡处理、新建加固砂卵石坝。最后,运用极限平衡法(毕晓普法和瑞典圆弧法以及改良圆弧法),对处理后的尾矿库稳定性验证。结果证明,处理后的尾矿坝稳定性满足要求。Based on the dam break incident in Suizhong tailing pond, strengthening measures were proposed in this paper. The measures included fill slope reinforcement for the initial dam, dewatering and flood control and cutting slope for the dam, and building a new sand and gravel dam for reinforcement. Finally, by checking the tailing dam stability situation after the treatment by using limit equilibrium method（Fellenius method, Bishop method and improved circular-arc method）, it showed that the safety factors under all the conditions meet the requirement, and the analysis results showed that using the treatment scheme was feasible.
