Abstract: Wavelet packet decomposition and reconstruction method was used to analyze the velocity response curve of stress wave obtained with the simulation of intact and defective anchorage system.Achor length and defect position were calculated based on the reconstructed velocity response curve of stress wave.The accuracy of this method was also verified.On this basis,the experimental results were analyzed,which further verify the rationality of the method was verified.This method provides a flexible and reliable method for stress wave response which cannot distinguish the time position of reflected signal directly.

Key words: wavelet packet, anchoring system, audio-frequency stress wave
