摘要
通过实例阐述基桩声波透射法检测容易产生误判的两种情况—非全断面的局部缺陷引起的误判和声测管变位引起的误判。在对误判原因进行分析的同时,强调基桩声波透射检测工作中,应重视缺陷的准确定位检测和原始波列的分析利用。
Two misjudges,caused by the local flaw with non full-face and the uhrasonic testing tube＇s deflection, are formulated for the pile＇s cross-hole sonic logging. At the same time, the accurated allocation for the flaw and the utility of original wave train are emphasized.
