| Abstract: | 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. |
