摘要：The scheme of Dalian Jinzhou Strait Bridge is taken as an example, which is a self-anchored suspension bridge. Employing the finite element program ANSYS, A three-dimensional finite element model for the bridge is established and the pile-soil-structure interaction is simulated using the merging pile model of equivalent embedded fixation. Dynamic characteristics and seismic response analysis of the bridge are carried out. Effects of Pile-soil-structure interaction on seismic response of the bridge are studied and comparative analysis is investigated between the bridge and anchored suspension bridge with the same parameters of self-anchored. Results show that Soil-pile-the structure interaction has the more obvious role on seismic response of large-span self-anchored suspension bridge. It makes displacement significantly increase, moment at bottom of tower slightly decline and moment of stiffening beam in middle of main span significantly increase. ? 2009 EJGE.
