摘　　要：利用在防渗墙中预埋的灌浆管,使用跨孔超声波法、单孔超声波法和超声波CT综合检测技术对某150 m深基础混凝土防渗墙浇筑质量进行综合检测,并进行了钻孔取芯和钻孔电视验证。结果表明,应用综合超声波检测技术对大深度基础混凝土防渗墙进行检测,是一种有效技术,检测准确度高,检测结果准确可靠。With the pre-embedded grouting pipe, a comprehensive testing is made with a detection technology integrated with the hole-crossing and single hole ultrasonic detections and the ultrasonic CT on the placing quality of a foundation concrete cutoff wall with the depth of 150 m, and furthermore, the verification is made with the methods of core-drilling and the drilling television imaging. The result shows that the integrated ultrasonic detection is an effective detection technology for testing of the foundation concrete cutoff wall with large-depth; of which not only the precision is higher, but the testing result is also correct and reliable.
