In the concrete structure, the stress may change with load and tempercture etc.For crack depth testing by NDT methods, the stress condition of crack surface must be considered, especially for deep crack.In this paper, the results by large concrete block test were got.It was compared the difference between several representative nondestructive testing methods at the different stress conditions.The results show that the tested crack depth may be underestimated seriously by phase inversion methodand propagation time method, and the surface wave method performs better when the compressive stress on the crack surface is equal to, or less than 5 MPa.
