Detection of Cracks on the Concrete by Surface Wave Method
The detection of crack is one of the main topics of the dam safety monitoring. The most used method of detecting the cracks now is to apply the ultrasonic longitudinal wave. But it cannot resolve many problems. We studied and developed the method of applying the surface acoustic wave to detect the crack depth in concrete. The maximal detecting depth of crack reaches 10m and it can carry out the testing on any surface of concrete structure. The paper discusses the detecting principle, measuring methods and instruments and some field detection examples.
