地震波CT在混凝土防渗墙质量检测中的应用

The Application of Seismic Wave CT to Qualities Detection of Concrete Cut-off Walls

摘要: 本文给出了一个地震波CT技术检测混凝土防渗墙质量的实例,其检测结果和部分墙体的钻孔取芯、土工试验和注水试验进行了对比,结果表明地震波CT技术在检测混凝土防渗墙质量时快速无损,准确可靠,在防渗墙质量无损检测中有广阔的应用前景。

Abstract: Plastic concrete cut-off wallsare underground concealed work, playing a decisive role in seepage control, and the quality of cut-off walls directly affects the anti-seepage effect. The seismic wave CT may be an effective way to detect the quality of cut-off walls. We applied the seismic wave CT technology to detect concrete cut-off walls. We also compared the seismic CT results with the borehole core, geotechnical test and water injection test. All show that the seismic wave CT is a fast, accurate and reliable method to detect the quality of concrete cut-off walls. Seismic wave CT has a broad prospect in the nondestructive quality testing of concrete cut-off walls.
