摘　　要：马钢姑山铁矿采场东帮人工采掘高边坡由于受河水和地下水的较大动水压力、静水压力的长期作用,和大爆破采掘施工触发强烈地震的频繁影响,局部坡段日益面临失稳滑坡的极大危险.本文运用有限元方法对东帮高边坡的稳定性问题进行了分析,提出了4种加固方案.结合加固工程的经济性、环境的影响性以及矿山的可持续发展与生产安全性等,对每一方案进行综合评价,从而确定方案三为最佳方案.Under the effect of hydraulic pressure and strong quake caused by blasting while mining, the stability of the high slope of the eastern dike of Gushan mine Magang is declining. Studies on the stability of the high slope by the Finite Element Method. 4 design programmes are proposed for cut-off seepage, slope rein- forcement and mining safety. The programme 3 is verified to be the best one.
