Application of Wavelet Analysis in Shallow Defects Testing of Pil
Dongzi Pan · Nondestructive Testing · 2005
By analyzing the response signal of pile when it has shallow defects with wavelet transformation, the reflecting characteristics of the stress wave hiding in the original signal is obtained. This method can locate the shallow defects of pile accurately and be verified by numerical simulation experiment. The result of in-situ test is in good agreement with numerical simulation and it shows that this is an effective method and can be used in shallow defects testing of piles.
