摘要
通过现场测试数据和该区已有资料,运用FLAC-3D软件,模拟分析拟建场地高层建筑和地下车库的CFG桩复合地基作用机理和沉降规律,以及两者在建筑物地基变形方面的作用关系。通过模拟CFG桩变形情况以及和实际测量所得到的沉降数据进行对比,得到了CFG桩的实际沉降分布,对类似条件下CFG桩复合地基设计具有指导意义。
Through field test data and the data existed, the article uses FLAC-3D software to simulate and analyze the mechanism of CFG pile composite foundation settlement laws proposed high-rise buildings and underground garage space, as well as the role of the relationship between the two in terms of the deformation of the building. The obtained data is compared by simulation of settlement of CFG pile deformation and actual measurement, which obtained the actual CFG pile settlement distribution,has the instruction significance to the design of CFG pile composite foundation under similar conditions.
