摘要
以广东某高速公路的混凝土东灌注桩的工程检测实践,分析声波透射法检测混凝土灌注桩缺陷的声学参数特性,总结出常见的缺陷类型特征,提出对声波透射法检测混凝土灌注桩完整性的一些见解。
Based on some engineering testing examples, the paper analyzes the acoustic parameters features during the concrete perfusion pile detection by using the sound wave transmission method, and sums up the common type of defect features. The author puts forward some opinions for sound wave transmission method testing of concrete perfusion pile integrity.
