| Abstract: | In this study, the authors analyzed the vibration of the structure under the underwater blasting using evolutionary spectra. The results showed the frequency property of vibration and the evolu- tionary processions of instantaneous average energy in the domain, which is consistent with monitoring results in field test. The study is a beneficial attempt for analyzing explosion seismic using the evolutionary spectral method. |
