| 摘 要： | 尾矿坝是金属矿山和非金属矿山重要的生产设施,同时又是重大的危险源,为了保证尾矿库的生产安全,需对尾矿库进行系统稳定性评价。采用邓肯-张模型对陶家沟尾矿坝进行了三维静力和动力有限元分析。得到坝坡的静力稳定最小安全系数为1.26,地震反应结束时的动力边坡稳定安全系数为1.16。分析结果表明,陶家沟尾矿坝在静力状态下是稳定的,在动力作用下尾矿坝的边坡仍然是稳定的,此研究可为尾矿坝施工设计提供参考。

| Abstract: | In order to ensure the safe production of a tailing dam,the systematic stability assessment for it is needed.The 3-D finite element analysis is performed by applying Duncan model to evaluate the stress and deformation of the tailing dam of Taojiagou project.The results show that the minimum safety factor for static stability of the dam slope is 1.26,and for dynamic stability of the dam slope,it is 1.16,indicating that the tailing dam of Taojiagou project is stable both in static state and dynamic action.The... |
