几种桩基计算方法的比较分析

Comparison between several calculating methods of pile foundation

选取了几种具有代表性的桩基分析方法,分别是Poulos边界积分法、Randolph方法、Poulos-Randolph综合法、Butterfield边界单元方法、Chow混合方法、W.Y.Shen变分方法和改进变分方法,通过编制相应的计算分析程序,力求从方法本质和原理上,以及各方法计算结果上来对各种计算方法进行比较分析。

The paper chooses 8 kinds of representative analyzing methods of pile foundation, they are Poulos boundary integral method, Randolph method, Poulos Randolph method, Butterfield boundary dement method, Chow mixing method, W. Y. Shen variational method, improved variational method, through establishing relative calculating procedure, the paper try to compare several calculating methods from aspects of method base and principle as well as calculating results.
