摘要

CFG桩（水泥粉煤灰碎石桩）复合地基是新近发展起来的一项地基处理技术，具有承载力提高幅度大，地基沉降小，适用范围广，造价低，施工方便等特点。阐述了CFG桩复合地基加固机理及沉降模式，详细讨论了其沉降计算，包括它的计算厚度、影响因素、压缩模量选取及附加压力计算等。提出按变形控制理论进行变形计算有其优点，但仍有很多工作要做。

Abstract

Composite foundation of CFG piles is a lately developing technique in ground treatment and characterized by great bearing capacity

little settlement in ground treatment

wide scope of application

low cost

convenient construction

etc. The consolidation mechanism and settlement form of composite foundation of CFG piles

are elaborated. Analysis of settlement was discussed in detail including computing thickness

influential factors

modulus of compressibility choice and computation of additional pressure

etc. Although some merits were put forward based on the theory of settlement control while computation of settlement

there are a lot of works to be done.
