摘要

近年来刚性桩复合地基在工程中的应用日益广泛，但是，对该种复合地基在动力荷载下，尤其在是地震作用下的动力响应性状却研究很少。考虑地震作用下土-桩-上部结构之间的相互作用，采用三维有限元方法，对刚性桩单桩复合地基的地震响应进行时域内的模拟计算与分析研究，分析了这种复合地基与桩基础地震响应的差异，并对影响刚性桩复合地基抗震性能的一些因素进行了研究，得出了一些对刚性桩复合地基的抗震设计有参考价值的结论。

Abstract

Rigid pile composite foundations are getting more and more application to construction engineering. However

the research on their response under dynamic loading

especially under earthquake loading

is quite limited. Now the seismic response analysis in time domain is performed with 3-D finite element method

taking into account of the interactions among soil

pile and the superstructure. The differences between rigid pile composite foundation and pile foundation in seismic response are analyzed. Some parameters influencing the anti-seismic behavior of rigid pile composite foundation are studied. Based on these analyses

some conclusions which may be of some value for anti-seismic design of this type of composite foundations are drawn.
