Application of Wave Velocity Method to Checking on Quality of Anti-Seepage Wall

Ultrasonic method and surface wave method are introduced to check on the quality of anti\|seepage wall and their principles are also discussed in this paper. A water conservancy project is examined by using ultrasonic method and surface wave method. It is proved that ultrasonic method and surface wave method can accurately check on the quality of anti\|seepage wall and the cost is decreased.
