The Practice Use Of The CFG Pile Composite Foundation

The area becomes deficient for construction is a vary important problem inconsistent with the development of basic construction scale. So the poor foundation reinforcement get more and more important especially evidence in the Pearl River delta district. It's synthesis and complex problem to deal with ground treatment. It not only require for engineering construction thinking about perimeter environment but also with experience in ground treatment district.In recent years, with the development of technology of the foundation reinforcement, the technology of composite foundation become more and more popular used. CFG is one of the new foundation reinforcement technology, for it low cost, easy construction, high carrying ability, strong flexibility, it become more and more spread and used.In this article, the author combine the experience of the engineering practice and the contribution of the former people, analyze the mechanism of the CFG composite foundation, the calculate method of carrying ability, and the influence of the vary parameter using the finite element method; and also do the analyzing of reliability, expatiate the produce of the construction and the way of the construction design, and at last summarize it in the practice of the projects.In this article, the author calculate the carrying ability and analyze the influence factor, in order to validate the design, guide the construction, so that it can make the economy and society contribution to the real projects used, and provide the impersonality gist for the farther theory research.
