Discussion of Equivalence Relation between Traffic Vibration and Blasting Vibration by Energy Method

QIN Yu-zhang,SHU Da-qiang,HE Wen-jun(State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University,Wuhan 430072,China)  
Based on the equivalent energy content inputted to structures and buildings by traffic vibration and blasting vibration,a conversion formula about traffic vibration velocity and equivalent blasting vibration velocity was derived.A method of assessment of the traffic vibration safety problems was discussed with reference to the blasting safety standard.According to monitored traffic vibration velocity data,the equivalent blasting vibration velocity was converted.The results shows that the maximum input energy densities of traffic vibrations in most conditions are tantamount to normal tunnel blasting excavations.The impact of vibrations on some structures and buildings induced by some heavy vehicles are in the same magnitude as which induced by drilling and blasting.
