摘要
四川瀑布沟水电站隧洞掘进生产性试验爆破过程中,通过爆破震动观测,全面了解与分析了各种爆破方法和施工部位的爆破震动形成机理、传播规律及响应特性。探讨开挖爆破对隧洞本身及相邻隧洞的震动影响,据此提出能够有效实施的洞室控制爆破方法。
Through the blasting vibration observation, the paper overall comprehends and analyzes a variety of blasting methods and forming mechanism, propagation law and response characteristics induced by blasting vibration during the productive test blasting in the tunnel excavation of Sichuang Pubugou hydropower station. Based on discussion of the influence of excavation blasting for the tunnel itself and adjacent tunnel, effective cavern control blasting method is proposed.
