Abstract: In order to study the effect of ground motion characteristics on seismic performance of pile-supported wharf in liquefiable ground, a numerical model for seismic response analysis of pile-supported wharf with all-straight piles was established. The key dynamic response characteristics of pile-supported wharf under earthquakes were systematically analyzed, and the seismic performance demand indexes of pile-supported wharf were determined. The influence law of ground motion characteristics on seismic performance demand index was revealed. The results show that the weakness of bending, shear, and compression of pile foundation of pile-supported wharf occur at the junction of bearing layer and upper soil layer, bank elevation, and sand layer and upper soil layer, respectively. The peak acceleration, spectrum characteristics, and input direction of ground motion significantly affect the seismic demand of various performance indexes of pile-supported wharf. The flexural, shear, and compressive performance demand of pile-supported wharf are controlled by the bending moment at the top of the pile closest to the land side, the shear force of each weak link and the axial force at the junction of sand layer and upper soil layer, respectively. The seismic ductility demand is determined by the displacement demand at the top of the pile closest to the sea.

Key words: liquefiable ground, ground motion characteristics, seismic demand, pile-soil interaction, pile-supported wharf
