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.
