【Abstract】 Both velocity and absorption of frequency spectrum of seismic wave are related with the physical properties of the medium through which the seismic wave travels.A method making use of both travel-time and spectrum analysis of seismic data used to analyze seismic data obtained from concrete elements test is presented.This method can be named as time-frequency analysis.A program based on this method is designed and applied to process seismic data obtained from concrete model and practical test data.The results show that the resolution can be improved with the time-frequency analysis and more accurate assessment of the quality of the concrete elements can be achieved.更多还原
