挤扩支盘桩在地铁抗浮工程中的设计与施工

Design and Construction of Piles with Squeezed Flanges for Resisting Floating in Metro Projects

挤扩支盘灌注桩应用于结构地基的抗浮,可解决许多技术缺欠,使地基起到抗压和抗拔的双重作用。介绍挤扩支盘抗拔桩在地铁车站抗浮工程中的设计应用、施工方法和力学特性,以及在抗浮工程中的优越性及经济性,为保证地铁车站的安全运行打下坚实的技术基础。

Piles with squeezed flanges are employed to resist floating for the structural foundation that help solve many technical problems and make the foundation much stronger against compression and pulling. In this article, the design and application, construction method, mechanical characteristics of squeezed flange piles for resisting floating in metro projects and their advantages in practice are introduced. The article is hoped to provide a technical basis for the safe operation of subway stations and for similar underground anti-floating design and construction in the future.
