摘　　要：某铁矿生态修复工程采用尾砂胶结固化方式对露天采坑进行回填,计划在露天坑周边建设充填站,为论证边坡及充填站安全可靠性,本文采用极限平衡分析和数值模拟方法,对充填站荷载作用下的边坡稳定性进行了计算分析。计算结果显示,该充填站所处的边坡在回填至-354 m时为基本稳定,在充填至-300 m工况下处于稳定状态,为确保边坡及充填站安全,建议加强该充填站所在区域边坡监测,确定所在区域边坡稳定前提下进行建设。A iron mine ecological restoration project is to backfill the open-pit using tailings cemented solidification method.It is planned to build afilling station around the open-pit.In order to demonstrate the safety and reliability of slope and filling station,the limit equilibrium analysis method and the numerical simulation method were used to calculate and analyze the slope stability under the load of the filling station.The calculated results show that the slope under the load of the filling station is basically stable when the open-pit is backfilled to-354 m,and the slope is under stable state when the open-pit is backfilled to-300 m.In order to ensure the safety of the slope and the filling station,it is recommended to strengthen the monitoring of the slope where the filling station is located.And the construction should be carried out under the premise that the slope in the region is stable.
