【摘要】水泥粉煤灰碎石桩（CFG桩）具有施工速度快、工期短、质量容易控制、工程造价低廉的特点，目前已成为应用最为普遍的地基处理技术之一。近年来随着其理论和工艺的不断提高，其应用范围愈来愈广，其中在小高层建筑地基处理中应用较多，在一些地区已应用到了31～35层建筑。本文通过利用单桩承载力计算复合地基承载力工程实例，介绍CFG桩的设计、施工与存在问题。

In recent years, with its theory and the continuous improvement process, and its increasingly wide range of applications, including high-rise building in a small foundation to deal with the application of more, in some areas has been applied to the 31 ~ 35-storey building. In this paper, through the use of single pile bearing capacity of composite foundation bearing capacity of the project an example, CFG p
