摘要
采用极限平衡法和有限元重力加大法,结合近北庄铁矿Ⅴ号排土场的实际情况,对该排土场东侧边坡进行稳定性分析。结果表明现有的边坡处于不稳定状态,随时有发生滑坡的可能。通过增加2个20m的安全平台,使边坡的安全系数大于安全储备系数1.15,可以保证矿山的安全生产,对工程实践具有一定的指导意义。
Based on the actual situation of No. 5 dump in Jinbeizhuang Iron Mine, the dump slope stability at the eastern side is analyzed by using the limit equilibrium method and the finite element gravity increasing method. The findings demonstrate that the dump is unstable the dump may landslide at any time. By adding two 20-meter safety platforms, the safety factor can be greater than 1.15. In this way, the safety of mine production can be guaranteed. Besides, it is significant for the engineering practice.
