采用岩石动力学分析水工隧洞爆破开挖形成的应力波在已开挖洞段围岩中的传播及引起的动应变效应,阐明水工隧洞爆破开挖条件下的岩爆形成机理,并提出了一些有效的防治措施。
Rock dynamics is used to analyze the propagation of stress wave induced by blasting in hydraulic tunnel excavation and its dynamic strain effect in surrounding rock of excavated section. The formation mechanism of rock burst under blasting excavation of hydraulic tunnel is clarified. Some effective prevention and control measures
