(浙江大學建筑設(shè)計研究院，杭州310027)[摘要] 把三維復合單元法和分區(qū)積分技術(shù)引入樁筏基礎(chǔ)的研究分析中，使大型樁筏基礎(chǔ)考慮樁-土-筏共同作用的整體三維有限元法分析成為可能，并對一個實際的大型樁筏基礎(chǔ)進行了計算，研究了樁筏基礎(chǔ)的應力傳遞特征和變形分布情況，將計算結(jié)果與規(guī)范法等計算結(jié)果進行比較。

( The Architectural Design and Research Institute of Zhejiang University, Hangzhou 310027, China)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
