摘要

基于Mindlin位移解，对成层土中的单桩及桩周土作离散化处理，建立了桩土之间有相对滑移和土体存在极限阻力的单桩分析模型，其中桩体沉降采用有限差分法求解，而桩周成层土体的沉降则利用考虑了各单元土体相互影响的ML法计算。两部分之间通过位移协调建立联系，并采用迭代法求解，建立的模型具有较严密的理论基础，且能反映真实的土体分层特性，算例结果亦表明有较高的计算精度。

Abstract

Based on Mindlin’s displacement solution

through discretization on single pile and surrounding layered soil

a single pile analysis model is developed by considering the relative slipping and the limit shear stress in the slip zone between pile and soil. Thereinto: the settlement of single pile is solved by finite difference method; and the settlement of surrounding soil can be calculated by ML method considering the effect of the soil modulus at all soil layers. The two parts can build relation according to displacement coordination relationship

and used to calculate. This method owns rigid theoretics; and it can feedback the real characteristic of soil mass. Through a case study

it has shown that this method is rational.
