Abstract
In the large hydraulic concrete structure that conventional nondestructive testing technique can’t implement quantitative detection, using steady Rayleigh wave technique can acquire various characteristic parameters of concrete. The paper introduces the principle and detection system of steady Rayleigh wave technique systematically, and makes detection experiments to introduce steady Rayleigh wave e technique and application progress of it in quality of large hydraulic concrete and nondestructive detection of crack depth. The practice proves that steady Rayleigh wave detection technique has the characteristics of strong antijamming capability and higher detection precision.
