Abstract: The rapid development of international trade speeds up the construction of port projects,and puts forward higher requirements for the seismic performance of port engineering. Pile-supported wharf, as one of the most common types of port engineering, has been widely used in port engineering construction. At present, there are few studies on the simplified method for seismic analysis of pile-supported wharf and the influence of pile foundation characteristics on its seismic response. In this study, a simplified analysis model of the pile-supported wharf was provided, and the influence of the characteristic parameters of the pile foundation on the seismic response was analyzed by using open-source OpenSees computational platform. The computed results show that:1) The elastic modulus of reinforcement has a little influence on the seismic response of the pile foundation; 2) The reinforcement stage of the steel bar plays an important role in the bending moment bearing capacity after the section reaches the yield curvature; 3) The increase of concrete compressive strength can reduce the peak displacement of the wharf; 4) Larger or smaller concrete compressive strength and steel bar yield strength are not conducive to the dissipation of seismic energy of the wharf structures.

Key words: pile-supported wharf, soil-pile interaction, moment-curvature, seismic response, parameter analysis
