声波透射法测桩中容易误判的情形

Misjudges for Pile's Cross-hole Sonic Logging

利用声波透射法检测桩身完整性,准确度相对较高,但缺陷范围的大小、缺陷在桩身所处的位置以及声测管所用材料的不同等,都会对检测结果产生影响,本文通过实例分析讨论容易误判的情形。

Transmission method using crosshole sonic logging pile integrity detection accuracy is relatively high,but the scope of the size of defects,defect location in the pile as well as the acoustic tube of different materials used,will have an impact on the test results, this paper through examples of analysis discuss the case of miscarriage of justice.
