Collected data from blasting vibration test is quite discrete. The technique of deleting error data and wavelet denoising are used to preprocess blasting vibration test data. In this study
standard residual sum of squares between the collected blasting vibration and the calculated fitted values using Sadovski formula are adopted as deviation basis; while wavelet denoising method is used to deal with the measured data. Particle swarm optimization algorithm (PSOA) was optimized for k and a of Sadovki formula of regression analysis. The results show that: wavelet denoising and particle swarm optimization algorithm reflect the real situation of blasting vibration test and thus improve sequentially simulation accuracy of blasting vibration test
so as to offer a good reference for blasting vibration test theory and engineering practice.
