浅谈夯扩桩的设计与检测

On the design and test of rammed-expand pile

介绍了夯扩桩又称载体桩,是一种以夯扩头支承力为主、以桩身侧摩阻力为辅的挤土桩,有其独特的施工特点,其设计和施工也与其他灌注桩有所不同。就夯扩桩的成桩工艺、优缺点、适用条件、承载力的计算进行了分析,并通过工程实例提出了对其质量进行检测的综合方法,从而确保成桩质量。

It introduces that rammed-expand pile also called bearing base pile is a kind of soil-pressed pile which orients the supporting power of rammed-expand pile head and the side friction of pile as supplement. It has its unique construction features and its design and construction is different from other cast-in-site piles. It analyzes the piling technique, advantages and disadvantages, suiting conditions, load capacity calculation of rammed-expand pile and puts forward the comprehensive method to test its quality with projects, so as to guarantee the quality of piles.
