中文摘要:
      本文对会理县小团山尾矿库地质勘查资料整理,合理概化了坝体主轴剖面,采用等效粘弹性模型,对处于洪水工况下的小团山尾矿坝用GeoStudio有限元软件进行数值模拟研究,研究了该尾矿坝在EI Centro地震波作用下的反应加速度、位移变化、液化范围、安全系数、动力稳定性的规律,研究结果显示该尾矿坝可在洪水工况下稳定运行,为其他尾矿坝的动力稳定性分析提供参考。
英文摘要:
      in this paper, the geological exploration data of Xiaotuanshan tailings reservoir in Huili County are arranged, the main shaft section of the dam body is reasonably generalized, and the GeoStudio finite element software is used to simulate the Xiaotuanshan tailings dam under flood condition by using equivalent viscoelastic model. The response acceleration, displacement change, liquefaction range, safety factor and dynamic stability of the tailings dam under ei Centro seismic wave are studied. The results show that the tailings dam can operate stably under flood condition. It provides reference for dynamic stability analysis of other tailings dams.
