%X The seismic responses of the piles in a wave-current field
are studied by theoretical analysis and finite element simulation.
Besides the wave-current force and hydrodynamic pressure on the
piles in the wave-current field, the results of the model test
show that the vortex-induced lateral force should also be considered. The
finite element simulation of a platform with four piles in the
wave-current field under seismic action is carried out. It is shown that
the seismic responses of the piles are magnified by water. Except for the
acceleration along piles, the relative displacement and shear force and
moment are increased significantly under the combined action of the wave-current force and
the vortex-induced lateral force. And it is also indicated that the
failure at the bottom of piles occurs easily under the seismic action.
