| 摘 要： | 针对尾矿坝的动力响应问题,基于完全非线性动力分析理论,采用Flac3D软件,分析计算了某尾矿库1#副坝地震响应,获得了该尾矿坝在地震作用下的加速度放大系数、动位移及库区液化的动力响应特性。结果表明:在动力荷载作用下,坝体竖直方向和水平方向加速度放大系数分别为1. 47和2. 91,具有较大的安全储备;坝体水平方向位移变化不大,且液化范围较小,不影响尾矿坝的整体稳定性。

| Abstract: | For studying dynamic response of tailings dam,the seismic response of the 1# auxiliary dam of a tailings reservoir was calculated with the Flac3D based on the fully nonlinear dynamic analysis theory,and the acceleration amplification coefficient,dynamic displacement and the dynamic response characteristics of liquefaction in the reservoir were obtained. The results showed that the action of dynamic load led to the dam with acceleration amplification coefficients for the vertical direction and horizontal directions at 1. 47 and 2. 91 respectively,as well as with more safe reserves. It is shown that little change in the horizontal displacement for the dam and a small percentage of liquefaction,resulting in little impact on the overall stability of the tailings dam. |
