摘　　要：针对庙沟铁矿二期尾矿库子坝在雨季出现大面积流砂冲沟等影响坝体整体稳定性的具体问题进行深入分析,并结合沉降、滑塌和渗流等影响坝体整体稳定性的不安全因素,提出加强坝体位移观测、修筑并维护排水沟、进行库区绿化和加强安全管理等一系列治理方案。In rain seasons rainwater often causes big--sized trenches on Phase--II tailings dam top and slope surface that influences integrated stability of dam. This problem is analyzed in details. On the basis of analyzing factors such as settlement, collapse and leakage that damage the stability of dam, a series of measures including surveying of dam body shift, digging and maintaining of drainage trenches, green making of dam area, enhancing of safety management are recommended to keep safety of dam.
