桩基质量分析及动力检测方法研究

Study on Quality Analysis and Dynamic Testing Method for Pile Foundation

本文分析了两类常见的沉管灌注桩和人工挖孔灌注桩的工艺特点，桩基质量问题的产生原因及动力检测方法，指出要准确地判断两类桩基质量问题，必须准确计算缺陷的位置，对桩基的工艺特点和施工过程有深刻的认识，对动力检测理论有透彻的理解。同时。

,This paper discusses the technics features of shaft injection pile and manpower digging hole infection pile, and analyzes the cause for pile quality question and the dynamic testing method for pile quality. It is necessary to calculate accurately the location of defect , to know well about dynamic testing theory, technics features and construction process of pile foundation for judging the quality of the two types of injection piles.This paper also specially discusses the dynamic testing particularity of manpower digging hole injection pile.
