Abstract The test and analysis of blasting vibration effects play an important part in the assessment of blasting safety and effect, but there are still many inadequacies in the data processing and analysis for the blasting vibration signals collected. On the basis of interpretation of the basic principles of wavelet transform, theoretical explanation of energy analysis method is given and the wavelet packet energy decomposition of an example of blasting vibration signal is carried out. The results show that wavelet packet energy decomposition method can better reveal the partial characteristics in different frequency bands of the signal and lay the theoretical basis for reliable assessment to construction blasting vibration response.
