摘　　要：结合工程实例介绍了CFG桩复合地基在高层建筑中应用情况,现场原位试验表明CFG桩加固地基能大幅度地提高天然地基的承载力,对软弱地基承载力的提高尤其明显,和传统灌注桩基础相比工程造价节约50%以上,经济效益显著,值得推广应用。Combined with a project example,presents the application of cement flyash gravel pile(CFG) composite ground in high-rise buildings,in situ tests showed that the CFG can greatly improve the bearing capacity of natural foundation,the bearing capacity of soft foundation improvement is especially obvious,compared with the traditional pile foundation,the construction cost is saved by more than 50%,significant economic benefits,it is worthy of popularization and application.
