摘要

水泥土搅拌桩（DMM）在高速公路工程中得到广泛应用

人们也希望能对该复合地基在路堤荷载下的地基的变形深入了解

其数值分析是一种重要的方法。但是

采用三维有限元进行数值模拟在高速公路工程中容易造成数组过大

计算时间并且收敛性比较差

因此把三维问题简化为二维问题是众望所归。在把三维问题简化二维平面问题简化计算时

最重要的是参数的折减。基于水泥土搅拌桩复合地基的特性

结合理论分析提出了一种参数折减的方法。并依据连盐高速公路实测的数据验证了该参数简化方法的可行性。

Abstract

The cement-soil mixing piles are widely used in expressway engineerings

so it is urgent that the behavior of cement-soil mixing piles composite foundation is deeply comprehended. And the FEM numerical analysis is an important method. The three-dimension FEM easily leads to the big scale matrix

long calculation time and bad convergence; so the planar simplified method is necessary. During simplification

the transformation of parameters is the key problem. The paper brings forward a parameter transformation method by characteristics of the composite foundation and theoretical analysis. Finally

the method is validated by the observed data of Lian-Yan Expressway.
