| 摘 要： | 将桩的上部结构、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,筏板计算采用享奇中厚板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进行共同作用的空间,分析并编制了相应的程序.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 super structure members have been represented by means of twonode space beam elements with six degrees of freedom per node taking account of the effect of axial-flexural interaction.The plate bending element with three degrees of freedom per node has been employed to represent 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 are established,which makes it possible to accomplish the spatial analysis of the superstructure-pile/raft-foundation soil mass interaction. |
