目前,CFG桩复合地基已广泛应用于多层、高层、超高层以及工业厂房等工程的地基处理中,并取得了非常好的工程成效和经济效益,但其相关的理论及设计方法还有待进一步完善,因此开展CFG复合地基相关理论及工作性状研究工作无疑具有重要的工程应用价值。从具体工程实例入手,利用ABAQUS软件进行了CFG桩复合地基在轴对称竖向荷载作用下的三维有限元模拟,并与现场静载荷试验结果进行对比,分析了二者偏差的原因。
At present, CFG pile composite foundation has been widely used in the foundation treatment of multi-story, high-rise, super high-rise and industrial plants and other projects, and has achieved very good project results and economic benefits, but the related theories and design methods have yet to be further Therefore, it is undoubtedly important to carry out research on the related theories and working properties of CFG composite foundation. Beginning with the concrete engineering example, the three-dimensional finite element simulation of CFG pile composite foundation under axisymmetric vertical load is carried out by using ABAQUS software, and compared with the field static load test results, the reason of the two is analyzed.
