【摘要】 地震荷载条件下坝体稳定性不足引起的溃坝事件是尾矿库的一种严重病患。本文采用不排水有效应力法对楚雄鱼祖乍尾矿坝进行了地震响应综合分析,从坝体动力反应及液化结果得出该坝在7度地震时是稳定的。但是,还应加强管理,在液化区采取加固措施。更多还原

【Abstract】 The tailing pond is the most important project of mine-enterprise, and it is also the biggest danger. Under seismic response, the dam-break by the poor stability is a serious disaster. In this paper, the effective stress method without drainage is applied for the response to earthquake of the Yuzuzha tailing dam comprehensive analysis. Dynamic responses from the dam and liquefaction results of the dam show that the dam is under 7-degree earthquake. But it suggests that the management should be reinforced and reinforcement may need to prevent from tailings dam failure in the liquefied zone.更多还原
