国内外超声波法检测判断准则的比较和推广应用

Comparison and Popularized Application of Ultrasonic Testing Judgment Criteria in China and Abroad

结合国内、外超声波检测超长大直径钻孔灌注桩的工程实践,分析比较我国相关检测规范与国际通行检测判断标准的异同,进一步总结归纳超声波法检测判断的准则,为今后在类似工程中推广超声波法检测技术提供借鉴。

By combining with the application of China ultrasonic testing method and international ultrasonic testing method in checking the bored piles with over-length and large-diameter,through analyzing and comparing China ultrasonic testing criteria and the criteria stipulated in international common cases,the ultrasonic testing judgment criteria is further summarized,which will provide the reference for the popularization of ultrasonic testing technology in the similar projects in future.
