摘要

粉喷桩复合地基常用的沉降计算方法精度较低，主要原因是附加应力计算方法不合理。针对粉喷桩桩身荷载传递规律及其受力特点，提出采用Boussinesq解和Mindlin解联合求解的方法计算附加应力场，推导了相应的计算公式，并进行了多种计算方法对比分析了加固区和下卧层附加应力分布特点。计算结果表明，提出的联合求解法计算精度高，合理可行。

Abstract

Because of the solution method unreasonable

the settlement calculation precision for the dry jet mixing pile(DJMP) is unconvincing. Based on the load transfer behavior and the characteristic of DJMP

using Boussinesq solution and Mindlin solution

the additional stress is calculated. Different calculation methods are used to analyse the stress distributing characteristic for stabilized layer and the underlying soft layer. The correlative formula is derived. Calculation result shows that the Boussinesq－Mindlin united solution method is reasonable and feasible.
