摘　　要：针对高压摆喷防渗墙目前检测存在的问题,本文介绍了弹性波CT技术检测的基本原理和过程,对某水库大坝高压摆喷防渗墙的质量进行检测,并对部分墙体进行钻孔取芯及注水试验验证,通过实例分析,结果表明弹性波CT技术在防渗墙质量检测中具有检测速度快,检测准确度高的优点,在防渗墙质量无损检测中具有广阔的应用前景。Aiming at the problems existing in the current detection of high-pressure swing jet grouting cut-off wall, in this paper, the basic principle and process of elastic wave CT detection technology are introduced. The quality of high-pressure swing jet grouting cut-off wall of reservoir dam is tested, and core drilling and water injection test are applied in the part of the wall. The results show that the elastic wave CT has the advantages of fast detection speed and high detection accuracy in the quality detection of the cut-off wall, and it has a broad application prospect in the non-destructive testing of the cut-off walls quality.
