STUDY ON SAFETY ASSESSMENT METHOD OF BLASTING VIBRATION RESPONSE BASED ON RESPONSE SPECTRUM

Through monitoring data of blasting vibration,relations between velocity response spectrum area of the blasting vibration(SR) and characteristic quantities of the blasting earthquake wave signal were analyzed.The influence of SR to vibration damage of the building structure and relations between them were studied.The results show that SR can comprehensively reflect the general effect of the blasting vibration and influences of structural dynamic characteristics to structural vibration damage.Then,a new method of the blasting seismic effect assessment was put forward that the SR was used as the blasting vibration safety assessment eigenvalue.The computation and the analysis of 132 groups blasting vibration data indicate that damage probability of general civil houses caused by blasting vibration increases significantly.≤5.5 can be used as a supplementary of blasting vibration damage safety criterion of the type II building.On this basis,the unified security criterion of blasting vibration was initially founded through introducing blasting vibration response spectrum safety factor of the building(Prs).In the unified security criterion,SR was as the blasting safety assessment eigenvalue and comprehensive effect of blasting vibration and vibration characteristics of the building structure were considered.
