摘　　要：为了研究声波透射法检测基桩质量的声学参数规律,制作了7组21根带缺陷的模型桩,通过声波透射法检测分析,得出了基桩质量缺陷严重程度与波速、波幅等声学参数影响的规律,为定量研究基桩质量完整性类别指标提供依据。In order to study the rule of acoustic parameters for detecting the quality of foundation piles with acoustic transmission method,seven groups of 21 model piles with defects were made.Through the detection and analysis of acoustic transmission method,the rule of the influence of the severity of the quality defects of foundation piles on the acoustic parameters such as wave velocity and wave amplitude was obtained,which provides a basis for the quantitative study of the quality integrity category indicators of foundation piles.
