摘要

面对越来越大量的工程应用，刚性桩复合地基的抗震性能成为亟待研究的课题。基于动力文克尔地基理论，提出了单桩复合地基的地震响应分析模型，推导了其地震响应的动力微分方程组，并构造了有限差分的求解方法，研究并探讨了不同影响因素变化下的地震响应性状，得到了一些有益于工程设计的规律性结论。

Abstract

As rigid pile composite ground is getting more and more applications in construction engineering

the research on its anti-seismic behavior becomes very urgent. This paper is concerned with the seismic analysis of type of composite ground. A model is proposed

based on the Beam on Dynamic Winkler Foundation theory

for the analysis of a single pile composite ground. The partial differential equations for its seismic response are derived and the finite difference method is applied to obtain the numerical solutions. Comparative studies are carried out to investigate the effects of various influence factors on the earthquake response of this type of composite ground. Valuable findings are obtained which can be of importance for its design.
