摘要
为了比较声波透射法检测基桩混凝土质量中声学参数对缺陷严重程度的反应敏感程度，制作了21根试验模型桩，经过试验结果比较分析表明，波阻抗率对缺陷反应敏感，并能区别不同严重程度，对探测缺陷及合理的判定基桩质量较为有利。
In order to compare the reaction＇s susceptibility of acoustic parameter on fault＇ s damage degree in detecting foundation pit concrete＇ s quality by sound-wave transmission method, this paper makes 21 testing molding piles, and shows by comparing and analyzing testing results that the reaction of wave impedance on the fault is sensitive and it can distinguish various damage degrees, which is propitious to detect fault an rational evaluate foundation pile＇s quality.
