The Foundation Design of the Terminal Building in Guangzhou New Baiyun International Airport

本文介绍了广州新白云国际机场航站楼在岩溶强烈发育地区的桩基础设计,这是中国目前在岩溶地区兴建的规模最大的民用公共建筑。本文讨论了各种基础方案的选择,介绍了摩擦桩的试验。航站楼的主体结构采用嵌岩冲孔桩,设计中采用的后压浆预应力管桩是首次在岩溶地区应用。

The foundation design of the terminal building in Guangzhou New Baiyun International Airport is introduced in this paper. The building is the largest civil architecture located in a strongly developed karst area in China. In this paper the selection of the foundation types are discussed and the tests of friction piles are introduced. The bored cast in place concrete piles embedded in rock were used in the main structure. The post grouting prestressed pipe piles adopted in the design were the first time applied in the karst area.
