RESEARCH ON SAFETY CRITERION OF VIBRATION BY DRILL-BLAST IN SUBWAY TUNNEL ENGINEERING
Based on the theoretical research and field test, the failure criteria for blasting vibration on subway tunnel engineering are summarized in the paper. It proposes the calculation formulas of the maximum allowable vibration velocity on intact and fractured rocks, on which the maximum allowable vibration velocity are given about the intact rock and fractured rocks. The safety criterion and effect of blasting vibration in runnel are studied, as well as the safety control and vibration effect on ground buildings by blasting excavation. On the other hand, the attenuation pattern of seismic waves is diversity under different methods of blasting excavation.
