BLASTING VIBRATION EFFECT ON TUNNEL EXCAVATION WITH HIGH GEOSTRESS AND FRACTURE ZONES

YU Yong-qiang1,LU Yao-bang1,YANG Xiao-lin2,GAO Fu-qiang2(1.School of Civil Engineering,Henan Polytechnic University,Jiaozuo 454000,Henan,China;2.Department of Civil Engineering,Luoyang Institute of Science and Technology,Luoyang 471000,Henan,China)  
To determine the blasting seismic wave propagation law and the impact on nearby rock or concrete lining,blasting vibration was monitored in the Guanjiao Tunnel excavation with high geostress and fracture zones.Through the regression analysis of field test dates,the propagation law of blasting seismic waves was received.According to this,security standards and measures were proposed to control blasting vibration velocity and reduce vibration hazards in fracture zones.
