预应力混凝土实心方桩在某泵站工程中的应用

Application of Pre-stressed Concrete Solid Square Piles in a Pumping Station Project

在水工建筑物非岩石基础处理的诸多措施中,预应力混凝土实心方桩在工期、投资、质量控制、承载能力和沉降量控制等方面都有一定的优势。本文依托某泵站基础处理工程,系统比较分析了预应力混凝土实心方桩和混凝土灌注桩两种处理方案,并优选适合于本工程的实心方桩处理方案,有效解决了基础承载力和沉降量问题,可供其它类似工程的基础处理参考。

Among the various measures for non-rock foundation treatment of hydraulic structures,pre-stressed concrete solid square pile is of certain advantages in construction time,cost,quality control,bearing capacity and settlement control.Taking a foundation treatment work of a pumping station project as example,two treatment schemes,i.e.the pre-stressed concrete solid square pile and the concrete cast-in-place pile,are compared and analyzed systematically.The pre-stressed concrete solid square pile scheme is selected,which effectively solves the foundation bearing capacity and settlement issues and is more suitable for this project.It provides useful reference for the foundation treatment of similar projects.
