Influence of Overlying Soil on Dynamic Response of Underground Structure

Abstract:

The article studies the influence of overlying soil thickness on dynamic response of underground stuctures by adopting the method of numerical simulation analysis. It carries on numerical analyses of dynamic response to the underground structures which overlying soil thickness is 0m、1.4m、2.8m、7.0m、14m、21m、28m. The results show that with the increase of overlying soil thickness, the horizontal displacement difference of bottom and top of side walls increases gradually. When the overlying soil thickness exceeds the height of underground structures, the displacement difference basically presents the rule of linear increase, while the displacement difference of the surrounding soil in the same depth do not change with the overlying soil thickness.
