文档介绍：摘要
随着我国近年来的经济和基础设施建设的发展,CFG桩复合地基技术在软土地基处理方面得到了越来越广泛的应用,并出现了很多理论和计算方法。但是由于影响CFG桩复合地基承载性状的不确定因素多、问题复杂且难度大,人们对它的认识还不够深入,使理论计算与工程实际存有较大差异,并且造成了在实际工程应用中的安全隐患或浪费,因此有必要对CFG桩复合地基承载性状进行进一步研究,使理论研究与实际相吻合并指导实践,从而达到安全适用、经济合理的目的。
本文以中华翰苑6#住宅楼楼为实例,介绍CFG桩加固软土的机理和复合地基的受力性状,概括CFG桩复合地基设计和计算的基本理论,利用这一原理,分析了桩体模量、桩长、置换率等对CFG桩复合地基承载性状的影响;说明了CFG桩在该地区进行地基处理的适用性和推广普及的可行性。

Abstract
With China's recent economic and infrastructure development, CFG posite foundation in soft soil treatment has been more widely used, and there have been many theoretical putational methods. However, due to impact of CFG posite foundation bearing capacity of the elements of uncertainty, the problem plex and difficult, it is not enough in-depth understanding of it, so that theoretical and practical engineering there a big difference and resulted in the practical application security risks or waste, it is essential to CFG posite foundation bearing capacity for further research to theoretical research and practical guide practice kissing the merger, so as to achieve security for, the purpose of economic rationality.
In this paper, the Chinese Han Court Building 6 # residential buildings as an example to introduce the soft soil CFG posite foundation of the mechanism and mechanical properties, general CFG posite foundation design and calculation of the basic theory, using the principle of pile model the amount of pile length, displacement rate on the CFG posite foundation traits; shows CFG pile foundation treatment in the region to promote universal applicability and feasibility.
Keywords: CFG pile; composite foundation; raft; ground treatment
