摘　　要：论述沉管灌注桩常见断桩的形成机理,并以低应变反射波法对断桩实测波形进行定性分析,最后依据反射信号的幅值,用时域拟合曲线方法对桩身缺陷进行了量化分析。The defect-forming mechanism of the Cased-in-site Pile with Sunk Casing and it抯 test which based upon the theory of reflection wave with low strain are discussed in this paper. The quantitative analysis of pile defect is also studied.

关 键 词：沉管灌注桩 断桩 桩身缺陷 量化分析
