非线性地基上桩结构物空间分析

Space analysis of pile structures on nonlinear foundation

本文提出了桩结构物－非线性地基空间相互作用分析的迭代法和非线性有限元法．其中，桩基分析用ｐ－ｙ曲线法．结合实际结构物进行了大量的计算及比较分析，成果是令人满意的，可以付诸应用．

In this paper, an iteration method and a nonlinear finite element method are proposed,they are capable of dealing with space interactions between piles and nonlinear fundation soil,and are based on the method of p--y curve. The computation of actual harbour structures and comparative analysis show that the results are satisfactory and the methods proposed can be applied to static analysis of pile fundation.
