上部结构—筏—桩—地基共同作用分析

Analysis of the interaction between superstructure,raft, pile and soil

提出一种改进的、能够满足筏基自由边界条件的位移模式，用以分析上部结构—筏—桩—地基共同作用．数值计算表明，该位移模式有很好的收敛性，特别适用于纯桩—筏基础的计算，能大大减少计算工作量．

This paper presents a modified displacement function which can satisfy the need of free boundary condition to analyse the interaction between superstructure, raft, pile and soil. It is proved by numerical calculation that this method has very good converging capacity and method is particularly suitable for analyzing piled raft foundation.
