摘要

从桩-土相互作用的机制出发，建立了均质地基中PCC桩负摩阻力传递的弹性微分方程。提出了基于有限差分法的一种桩身位移的迭代算法，计算结果表明，该计算方法收敛性好，且符合实际情况。根据中性点定义得出其位置在桩身中下部，与以往的研究结果相吻合。结果还表明，PCC桩比等截面的实心桩有较小的沉降。

Abstract

Based on mechanism of pile-soil interaction

the elastic differential equation of negative skin friction in homogeneous ground is established. An iterative procedure on the basis of finite differential method to calculate displacement of a pile body is proposed. The computing results indicate that the procedure given in this paper is of good convergence and well coincident with reality. The neutral point appears below the pile body according to its definition

showing the agreement with the previous conclusions. The results also show that PCC pile has a small settlement compared with the solid pile of equal cross section area.
