The parameter language APDL of finite element software ANSYS was used to research the dynamic characteristics of pile-gravity wharf panel. The results show that: The dynamic and static calculation results of wharf panel’s internal force is almost the same under the wave slowly varying pressure action, and the dynamic magnification coefficient of wave slowly varying pressure is not obvious; The dynamic calculation results decrease rapidly with the frequency of wave impact pressure increasing, when the frequency of wave impact pressure much more than 80 Hz, the dynamic calculation results are about 0.2 times the static calculation ones.
