摘要
本文介绍了在声波透射法灌注桩检测中,对于声测管管距的偏移,采用多次逼进拟合法求解声测管管距的方法进行修正,有效地解决了声测管不平行对声波透射法的干扰,并提出了基于声速的CBV缺陷判据。
The following text will introduce a method for the correction of the deviation of acoustic pipe-distance in crosshole sonic logging by multiple-approach fitting. This method can minimize the influence of in-parallelling of the acoustic pipe embedded in pile. Moreover, the text will put forward the CBV Defect-Criterion based on acoustic velocity of pile.
