| 摘 要： | 在上部结构-基础-地基-支护结构共同作用体系中，每一组成部分对共同作用体系都有作用，支护结构也如此，以上部框架结构-桩筏基础-地基-排桩支护结构共同作用体系为对象，研究排桩支护结构对上部结构和桩筏基础的作用，代用二维非线性有限单元法对其进行了共同作用分析，分别研究了不同相对弹性模量，不同相对刚度，不同支护桩长度等因素对该作用的影响，试图寻找一种通过调整某些因素就可在一定程度上控制支护结构作用的方法。

| Abstract: | In a common action system consisting of upper structure, foundation structure, subgrade and supporting structure, every component is contributive to the common action system. Taking the common action system of upper framed structure, pile raft foundation, subgrade and pile row supporting structure as a study object, the contributions of pile row structure to the upper structure and to the pile raft foundation are studied, the common action is analyzed by means of a 2 dimensional linear finite element method, and the effects of different relative elasticity moduli, different relative stiffnesses, different lengths of supporting piles, etc., on the common action are studied to analyze the methods to control to some extent the contributions of the supporting structure through the adjustment of these affecting factors. |
