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．
The accumulation of elastic strain energy is the internal cause of rock burst, but the occurrence of rock burst often has the disturbance of external factors. According to the above analysis, the mechanism of dynamic disturbance on rockburst is analyzed. Then the rockburst of a diversion tunnel of a hydropower station is analyzed, and the influence of dynamic disturbance on rockburst is calculated by complex reaction theory.
