Abstract

Based on water level change, computing on the ABAQUS finite element software, taking the single-column pier as the research project, considering the nonlinear of the soil and the concrete, establishing the earthquake response analysis model of water level - single column pier - piles - soil, analyzing single-column piers. The results show that: there are some changes on relative displacement, acceleration, shear force, moment of the pier under condition of water level change, and its change rule is consistent basically except for the individual conditions. It is necessary not only to consider the influence of hydrodynamic pressure, but also to consider effect of water level change for guide bridge seismic design better.
