The dynamic responses of a new kind of sheet-pile wharf under horizontal seismic loads have been simulated by using the finite element method, and the influences of earthquakes' characteristics have been analyzed in detail. Compared with the traditional sheet-pile wharf, the separated relieving platform system has been adopted for the new wharf and the dock basin could be much deeper for larger ships. The results of the numerical calculation show that the separated relieving platform system is still effective under seismic loads, and the maximum internal force of structural elements doesn't change when earthquake acceleration reaches the peak value. With the increase of the earthquake peak ground acceleration value, the maximum internal force of structural elements all increases at different degrees, the amplification of the bending moment is the largest, those of tie rod's tension force and anchor wall's bending moment are a bit smaller than that of the front wall, and those of front pile and back pile's bending moment are the smallest. The amplification coefficients of all internal force under the Kobe wave loads are always bigger than those under the EL-Centro wave with the same PGA value, which indicates that, in addition to the earthquake wave peak value, the responses are also affected by other earthquake characteristics, such as spectrum, wave energy density and wave total energy.
