桩-土-结构相互作用研究综述及展望

Review and Prospects on Pile Soil Structure Interaction

鉴于桩-土-结构相互作用对结构物的动力特性及地震响应的影响,对国内外桩-土-结构相互作用研究历史和现状进行了总结。介绍了国内外桩-土-结构相互作用的四大类研究方法:震害调查、数值方法、理论分析方法和试验方法,并分析了各优缺点及存在的主要问题。最后指出接触面本构模型的完善、计算方法的改进、数值分析与试验相结合、震害调查和原型观测资料的收集、空间分析模型研究是桩-土-结构相互作用问题研究的发展方向。

In consideration of the influence of pile soil structure interaction on the dynamic properties and seismic response of structure,a summary is made on the former and current researches on pile soil structure interaction（PSSI） at home and aboard.Four major types of research methods for PSSI,the seismic damage investigation,numerical method,theoretical analysis method and the experimental method,as well as their strengths and weaknesses and related problems are reviewed.It is pointed out that the perfection of interface constitutive model,the improvement of computational method,and the combination of numerical analysis with experimental study,the seismic damage investigation and collection of prototype measurement data,and the spatial analysis model research are the trend of further research on PSSI.
