Characteristics of Blasting Vibration Response Spectrum Analysis and Its Application
Based on summarizing the characteristics of blasting vibration response spectrum, the blasting vibration response spectrum curve and the relationship between the blasting seismic wave signal strength (peak particle velocity) and frequency were discussed. The response spectrum curve reflects that the blasting seismic wave signal parameters such as amplitude and frequency have effect on the structural vibration response, and also reflects the relationship between maximum response of a series of difference characteristic structure under blasting vibration and structural free vibration period T, meanwhile, the spectral area was presented to describe variation characteristics of response spectrum curve, and the statistical calculation of experimental data was used to discuss the relationship between spectral area and blasting seismic wave signal parameters such as strength and frequency as well as structural vibration response. The prediction model of spectrum area was established depend on ratio scale disSR=K(R/Q1/3)-a. Finally, experimental data was used to discuss the relationship between spectral area SR and blasting seismic signal parameters wave strength, frequency and time as well as structural vibration response, and safety criterion about blasting vibration was initial established depend on spectrum area SR.
