单桩沉降的一种解析解法

An analytical solution for settlement of single pile

本文对桩侧及桩端采用不同的荷载传递函数 (t z曲线 ) ,并考虑桩侧土体强度沿深度线性变化的特性 ,推导了一系列单桩沉降的解析表达式 .计算结果可直接用于单桩分析 。

Different load transfer functions for pile shaft and pile tip are adopted in the analysis of settlement of single pile. The lateral soil strength is regarded as linearly varies along the depth. On this basis, a series of anlaytical solutions of settlement of single pile are deduced. The calculated results can be used to back figure the parameters of soil properties.
