摘　　要：坝体稳定性不足引起的溃坝事件是尾矿库常见的一种病患。本文以某尾矿库为工程背景,运用拟静力法分析了尾矿坝在地震条件下的稳定性,运用理正岩土软件对其结果进行必要的校核,得出影响运用该方法计算尾矿坝地震稳定性精确性的重要因素——超空隙水压力变化值,该变化值主要由坝体材料渗透性决定,在此基础上提出了相应的安全对策。The tailing pond is the most important project of mine-enterprise, and it is also the biggest danger. The slippage of embankment by the poor stability is common. The paper has disscassed the stability analysis about tailing pond in the earthquake with an example. The quasi statics method was applied. By the computer-software, the result was validated. The interstice stress is the most important factor that affect the earthquake stability, and it is decided by the material of the dam. Based the former result, the safety countermeasures are put forward was applied.

关 键 词：尾矿库 地震稳定性 拟静力法 安全系数
