Dynamic Coupled Analysis for Earthquake Response of Pile Foundations
Most of the analytical methods for estimating the earthquake response of pile foundations are based on the dynamics of the structure and consideration of seismic pore water pressure's influences on soil dynamic behavior (e.g. liquefaction, softening) is difficult. The objective of this paper is to describe a dynamic coupled analysis for earthquake response of pile foundations and investigate the effects of seismic pore water pressure's generation and dissipation on dynamic pile-soil interaction. According to the character of earthquake effect, soils and pile foundations, the research model of the earthquake response of pile foundations is established. The model can consider the dynamic pile-soil-structure interaction. Based on the basic dynamic equations for porous media, the dynamic coupled analysis with the model is recommended to predict the earthquake response of pile foundations. The equivalent linear approach is used to compute the approximate nonlinear response of soil. The calculation procedure is also reported in detail. Finally, using proposed dynamic coupled analysis theory and software for earthquake response of pile foundations, a pile foundation is calculated and such results as acceleration, vibration pore water pressure and subsidence are given and analyzed.
