摘要

以剪切位移法为基础，假定桩周摩阻力与桩-土相对位移之间为弹塑性关系，推导了柔性基础下刚性桩复合地基的沉降计算公式；通过算例，探讨了桩顶沉降、桩身应力、桩周摩阻力、中性层等分布规律，并将中性层位置及桩端应力等计算结果与有限元及差分计算结果比较，得到了相一致的结论，证明了所采用方法的正确性。

Abstract

A simplified analytical method is presented for nonlinear analysis of the behavior of composite foundation with rigid piles. An elastoplastic relationship between the shaft shear stress and the relative shaft displacementsis adopted. The development of settlement

skin friction

stress and neutral plane on piles is investigated through the proposed approach. Comparisons of the load-settlement responses the finite element and difference calculation methods are given to demonstrate the effectiveness and accuracy of the proposed analytical method.
