摘　　要：将随机共振理论应用于岩爆形成机制的分析,建立了周期力和随机动力扰动影响下的岩板结构演化方程,采用势函数方法探索了随机共振诱导岩爆发生的机制,并讨论了动力扰动能量向周期力能量的转移现象.研究表明,岩爆的发生机制可通过随机共振理论得到很好的解释.Random resonance theory was applied to analyze the mechanism of rockburst, and a evolvement equation of rock board undergoing periodic forces and random dynamic disturbance was established.Potential function method was adopted in searching after the mechanism of random resonance induced rockburst, and the phenomenon of energy transferring from periodic forces to random dynamic disturbance in rockburst process was also discussed.The research indicates that the mechanism of rockburst happened in underground engineering can be interpreted well by random resonance theory.
