摘要：

The finite element analysis model of Zhuziqing tailings pond is established by using the finite element method (FEM) analysis software ANSYS based on hydrological conditions, engineering geological conditions, tailings silt dynamic triaxial test results and the foundation rock-soil wave velocity tests results. Then it was studied that the dynamic characteristics and dynamic response of Zhuziqing tailings dam under seismic loads. Results show that dynamic shear modulus of tailings silt increase as dynamic shear strain decreasing and increase as the increasing of confining pressure or consolidation ratio under the condition of isotropic or anisotropic consolidation. But the variation law on damping ratio of tailings silt is just opposite to that of dynamic shear modulus. Results also show that under the dynamic peak acceleration 0.2g of seismic wave, response acceleration of Zhuziqing tailings embankment reached the peak at the time of 2.58s, and the response peak acceleration is 5.24m/s(2) at the top of this tailings embankment.
