摘要：

A study of the dynamic response of a circular bridge pier forced simultaneously by earthquake and wave-current actions is presented. On the basis of diffraction wave theory, the analytic solution for the diffraction of incident waves with uniform current on a circular pier is given. On the basis of the radiation wave theory, the analytic solution for the hydrodynamic pressures on a circular pier induced by combined earthquake and wave-current action is obtained. Further, the solution for the dynamic responses of the pier under combined earthquake and wave-current action is obtained by treating the pier as a cantilever beam governed by beam theory. Last, the effects of hydrodynamic force, wave force, wave-current interaction, and surface wave condition on the dynamic responses of the pier are investigated. The results may be used for engineering practice and further research.
