摘要：Crack has a strong influence on the integrity, impermeable property, durability and bearing capacity of hydraulic concrete buildings. Although ultrasound is the main nondestructive testing method of concrete crack depth at present, a large amount of engineering applications demonstrate that it is not suitable for the crack depth detection of the hydraulic structure concrete. This paper illustrated the basic principle of detection of concrete crack depth by surface wave technique and verified the feasibility of surface wave technique to detect crack depth by two engineering examples, including steady-state surface wave method and transient-state surface wave method. The practical results show that surface wave is a rapid and effective nondestructive testing method in the detection of crack depth of concrete, which will have a good application prospect.
