摘　　要：摘要在地基承载力要求较高,沉降变形要求又比较小的情况下,采用水泥粉煤灰碎石桩(简称CFG桩)复合地基处理技术可以达到良好的效果,同时又比传统的钢筋混凝土基础桩要节省大量的成本。结合北京新机场东航生活区工程实践,从CFG桩的勘察、设计、施工、检测、缺陷处理等方面进行了较全面的介绍和总结,为类似工程的设计和施工提供借鉴。Under the condition of high requirement for foundation bearing capacity and strict settlement deformation, cement fly-ash gravel (CFG) pile compound foundation treatment technique not only could realize favorable construction effect, but also requires lower construction cost than traditional reinforced concrete foundation pile. Based on the east terminal living area construction practice of Beijing Daxing International Airport, this paper introduced and summarized in details the exploration, design, construction, survey and defect treatment of CFG pile, providing references for the design and construction of similar projects.
