Abstract
To study the influence of pile-soil interaction on the seismic behavior of PHC piles, this paper takes the PHC pile in the soft clay as the research object, which is simulated by fiber beam element, and the pile-soil interaction is simulated by using equivalent embedded method and p-y soft clay soil spring which is under cyclic load, respectively. The seismic behavior index of pile foundation under limit state is obtained through applying the horizontal cyclic load on the pile top. The research shows that, with the different depth of pile, the hysteretic energy dissipation index and the displacement ductility factor obtained by the equivalent embedded model are about 2.2~2.5 times and 1.1~1.4 times of the p-y curve model respectively. While the yield strength and ultimate strength obtained by the p-y curve model are larger than those obtained by equivalent embedded method.
