[摘 要 ] 薄壁钢管离心混凝土管桩,简称TSC桩,具有穿透地质硬夹层能力强、抗锤击能力强、承
载力高、便于施工、能有效节能降材、造价低,且可以与其他不同桩型组合的特点,是最近发展起来的一
种新的沉桩形式。目前,薄壁钢管离心混凝土管桩在国内还处于少量应用阶段,相关规范不全,应用经验
较匮乏。以厦门汇金国际中心大厦TSC桩基施工为例,在概述工程地质条件的基础上,完成了工程桩基设
计,设计了施工工艺技术、桩基测试技术等,为后续该技术的推广应用提供了参考。

APPLICATION OF PRECAST HIGH-STRENGTH THIN-WALL PIPE PILE CONSTRUCTION
TECHNOLOGY IN HIGH-RISE BUILDING FOUNDATION
Xu Sun-jie
[ Abstract ] Thin-walled steel tubular centrifugal concrete pipe pile, referred to as TSC pile, has the
characteristics of strong penetration of geological hard interlayer, strong resistance to hammer, high bearing
capacity, easy construction, effective energy saving and material reduction and low cost, and can be combined with
other different pile types. It is a new type of pile sinking developed recently. At present, thin-walled steel tubular
centrifugal concrete pipe pile is still in a small amount of application stage in China, the relevant specifications
are incomplete, and the application experience is relatively lacking. The paper takes Xiamen Huijin International
Center Building TSC pile foundation construction as an example. Based on the overview of engineering geological
conditions, the project pile foundation design is completed, and the construction technology and pile foundation
testing technology are designed, which provides reference for the subsequent promotion and application of this
technology.

对混凝土及钢材需求量大,薄壁钢管离心混凝土
管桩(简称TSC桩),是最近我国建筑工程上采用的
一种新型桩材。
该材料有独特的优势,抗锤击能力强而节省造
价 [3],最大的优点在于可根据不同的地质条 件及设计
要求与其他不同桩型进行组合使用。
目前,TSC桩属于创新产品,其施工技术在国内
还处于探索阶段,尚无国家和行业的技术规范和标
准。为满足工程建设的要求,保证工程的施工质量,
