[摘要] 把三维复合单元法和分区积分技术引入桩筏基础的研究分析中，使大型桩筏基础考虑桩-土-筏共同作用的整体三维有限元法分析成为可能，并对一个实际的大型桩筏基础进行了计算，研究了桩筏基础的应力传递特征和变形分布情况，将计算结果与规范法等计算结果进行比较。

Abstract: The piles-raft foundation for finite element method and partition integration method was analyzed. It makes the global analysis oflarge piles-raft foundation for finite element method possible. The text calculates a practical large piles-raft foundation and studies piles-raft foundation's stress transfer and settlement distribution. The result is similar for practical situation.
Keywords: piles-raft foundation; finite element method; composite element method; partition integration method
