英文摘要	Methods for optimizing the prediction of waveform and estimation of peak particle velocity (PPV) of explosive vibration are presented in this study. A computational procedure based on Matlab programs and modified Sadaovsk Formula is also proposed in this investigation. Optimization for waveform prediction is based on the combination of wavelet packet analysis (WPA) and non-linear regression analysis (NLRA). In addition, an attempt has been made to investigate the validity using a relatively new method called non-linear numerical analysis (NLNA) to predict the PPV of explosive vibration. In order to estimate the prediction accuracy, the field blasting experiment was conducted by Shandong University of Science and Technology. It has been proved that the WPA-NLRA-based modified Sadaovsk Formula has significantly better prediction accuracy than the widely used linear regression prediction method. Particularly, NLRA-based modified Sadaovsk Formula optimized by the multi-frequency-bands coefficients could achieve a more desirable accuracy in predicting the amplitude and dominant frequency, more stable and reliable compared with the single attenuation factor analysis method. It has also shown that the NLRA-based modified Sadaovsk Formula was obviously superior to the empirical formula in predicting PPV.
