摘要
尾矿坝作为金属矿山和非金属矿山的特殊构筑物,对其抗震稳定性常规的计算方法是采用拟静力法。但该方法在坝体破坏形式和机制方面的假定与尾矿坝的实际情况不同,只用拟静力法分析尾矿坝的地震稳定性是不够的,所以对尾矿坝进行动力分析是十分必要的。本文结合工程实例介绍动力分析的方法和步骤。
The quasi statics method is adopted for the normal calculating of anti-earthquake stability of tailings dam, which is a kind of special construction for metal or non-metal mine, but not enough because of the difference between the actual condition and the hypothesis in this method for the form and mechanism of dam damage. So it is necessary to conduct the dynamic analysis. The method and steps of the analysis are introduced with some project examples.
