摘要
为深入分析CFG桩复合地基承载特性,在深入探讨CFG桩加型,通过计算与实测曲线对比验证了有限元模型及参数的正确性与合理性,并以此为基础分析CFG桩的应力及变形,最后对CFG桩复合地基桩土应力比进行了探讨,获得了一些有益结论,对实际工程具有一定的指导意义。
In order to obtain the bearing characteristics of CFG composite foundation,based on the analysis of reinforcement mechanisms of CFG pile,the concrete courses of design and calculation for CFG composite foundation are introduced and the FEM model for CFG composite foundation is built under the engineering background.The validity and reasonability of FEM model and its parameters are verified by the comparison of computed and tested curves.Then the stress and deformation of CFG pile are obtained.Last the pile-soil stress ratio of CFG composite foundation is discussed.Some useful conclusions are obtained which are of leading meanings in the situ engineering.
