Li, L.; Wu, L.; Wang, X., and Cui, Z., 2015. Seismic response of underground structures in saturated soil based on the fluid-solid coupling dynamic formulation.

In this paper, the seismic response of the underground structures in the saturated soil is studied by ABAQUS, with the saturated soil being simulated by the pore pressure element based on the fluid-solid coupling dynamic formulation of fluid-saturated porous media. It is illustrated that by the end of the earthquake input, the value of Mises stress is maximal on the two bottom corners of the structure. The value of pore pressure and vertical displacement is large in the bottom area near the structure, and the value of pore pressure and vertical displacement is equal on two sides of the structure. The vertical displacement of the soil decreases with the increase of depth. The maximal seismic response occurs when the acceleration of the earthquake input is maximal.
