摘要：

Based on technology of multi-resolution wavelet analysis, a simulating method for velocity signals of blasting seismic waves was put forward. The simulation signals not only represent main characteristic parameters of blasting seismic waves, but also consider action of several dominant frequencies of sub-bands with large energy proportion. It is indicated by comparing structural dynamic response to simulation signals and measured signals that the method for simulating blasting seismic signals based on technology of wavelet analysis has great practical value and feasibility.
