simulation technology is used to detect the water flow in the wall,thereby completing the integrity inspection of the an-ti-seepage wall while detecting its permeability.The results show that in low-speed or high-speed abnormal speed models,the fluctua-tion of travel time residuals is significant and completely different.By using the enclosure method,the calculated permeability coeffi-cient is 0.14*10-6 cm/s,with an experimental depth of 15 m.By using the constant head method and depth of 15 m,the permeabili-ty coefficient calculated by this method is 1.88*10-6 cm/s.Based on the elastic wave CT forward simulation technology,it can effec-tively reflect the state of the anti-seepage wall.The anti-seepage wall permeability coefficient of the enclosure method is lower than that of the constant head water injection method.The proposed method can accurately detect the quality of anti-seepage walls.
