摘要(Abstract):

为确定关角隧道高地应力断裂破碎带地层的爆破地震波传播规律及其对邻近围岩(混凝土衬砌)的影响,对隧道开挖中的爆破振动进行了监测。通过现场测试数据回归分析,得到了该地层爆破地震波的传播规律。在此基础上,提出了断裂破碎带地层爆破振动速度的安全控制标准及减少振动危害的措施。
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.
