无桩尖夯扩沉管灌注桩的应用研究

Study on the Application of a New Type of Cast-in-Situ Pile

本文通过一个基础工程实例,详细地介绍了一种新型桩基——无桩尖夯扩沉管灌注桩的设计方法和施工工艺,经过与其它桩基的对比可以看出,这种桩基具有单桩承载力高、桩身用料少、施工方便等优点。

Through a practical foundation project, the paper makes a detailed introduction to the design method and construction process of a new type of pile-cast-in-situ ramming pedestal pile by pipe sinking without tip.This type of pile has a series of advantages such as greater load-bearing capacity for each pile, less consumption of materials for making the piles and easiness for construction and so on.
