| 摘 要： | 弹性应变能的积聚是产生岩爆的内因，但岩爆的发生往往具有外界因素的扰动．据些首先分析了动力扰动对岩爆触发的机理，然后结合某水电站引水隧洞岩爆实例，利用复反应分析原理计算了动力扰动过程对岩爆的影响．

| Abstract: | There are many factors having influences on rock burst,which can be divided into internal and external ones.- When large amount of elastic energy is accumulated in the rock mass, rock burst will be triggered by dynamic disturbance. In this paper,combining with a case of rock burst in a deep lying tunnel,the dynamic stress caused by the blasting is calculated by using Complex Analysis, then Griffith criterion and Mohr-Coluomb criterion are used to judge rock burst. The results show that,the dynamic disturbance not only can trigger rock burst,but also can change the scale of rock burst. Generally,if the wave of incidence is compressive,the scale of rock burst will enlarge,and if the wave of incidence is tensile,the scale of rock burst will descend. |
