Abstract:Aiming at the phenomenon that the peak value of blasting vibration velocity overran one which is allowed by security regulations,but not causing the damage of buildings,response rate,a integrative evaluation index of blasting vibration based on the three factors of blasting vibration and the selective magnifying function of buildings on blasting vibration signals with different frequencies,was used as safety criteria and to analyze the measured signals.The analysis showed that this method was closer to the practice,and the response rate is more effective than the two-factor(velocity-frequency) safety criteria.The analysis solved actual engineering problems,and also accumulated data for threshold ascertainment of response rate safety criteria.
