摘　　要：某炼钢工程主车间采用预应力管桩,持力层为密实砂层。如何通过对土层分析、理论计算、并结合现场试验,合理确定单桩竖向承载力特征值,通过介绍该车间厂房柱基桩和在线设备基础桩的设计过程,为类似项目中桩基设计提供了一种设计思路。Pre-stressed steel pipe pile is used for the main building of a steelmaking project.The force bearing stratum is dense sand.How to reasonably determine the characteristic value of the vertical supporting capacity of single pile by means of stratigraphic analysis,theoretical calculation as well as on-site test? The paper describes in detail the design process of the building column foundation pile and the in-line equipment foundation pile of the project,which provides a design idea for pile foundation of design similar projects.

关 键 词：密实砂层PHC桩 单桩竖向承载力特征值 标准灌入试验锤击数
