| 摘 要： | 将上部结构、基础与地基三者视为统一整体，上部结构考虑空间框架形式，筏板计算采用亨奇中厚板８节点等参数单元，桩土体系采用剪切位移法，考虑群桩效应的共同作用进行空间分析并编制了相应的程序．本文所采用的方法是一种空间分析方法，可推广到框一剪结构的空间分析．在求解时利用波前法使得效率极大提高．所编制程序具有一定通用性，适用于工程实践．

| Abstract: | This paper presents a novel modeling of super structure pile/raft soil mass system.The superstructure members were represented by means of two node space beam elements with six degrees of freedom per node which take into account the effect of axial flexural interaction.The plate bending element with three degrees of freedom per node was employed torepresent the raft.The pile vertexes flexural matrix can be obtained if pile soil mass system is analyzed by shearing displacement method.The interaction equation and the universal program of the whole system were established ,which makes it possible to accomplish the spatial analysis of the superstucture pile/raft foundation soil mass interaction. |
