Abstract:
A seismic effect is main harm in engineering blasting. By analyzing Seismic velocity and frequency of the main control factors of them, according to the data measured on the spot, the relation formula among Seismic velocity and dynamite and the distance between blasting fountain are obtained. Effects on buildings produced by vibration frequency and differences between blasting earthquake and natively seismic are analyzed. The calculation of blasting safety distance and selecting standard of breakage judge are studied and validated. The results of experiment and research indicate that we should attach importance to blasting seismic rules and effects on different buildings in order that basting techniques bring much economy benefits and reduce harm of blasting vibration as possible as much.
