Abstract: The basic critical principles and data processing of the side-hole acoustic transmission method are focused. Sidehole acoustic transmission method is a successful application of wave theory to the integrity test of piles. Some corresponding changes of acoustic transm ission method are made to accommodate the detection of the driven pile, which not only preserves the original advantage but also expands its testing scope.

Key words: driven pile, acoustic transmission method, non-destructive detection

摘要： 重点介绍了旁孔超声波透射法检测桩基的基本原理以及判定方法和数据处理。旁孔超声波透射法检测技术 是波动理论在桩基完整性检测中的成功运用,对旁孔超声波透射法做相应的改变来适应打入桩的检测,既保留了 原有方法的优点又扩大了其检测范围,适用于对打入桩的完整性检测。
