摘要
岩爆的孕育过程属于静力学机制,而岩爆的发生过程则属于动力学的研究范围。本文总结出声发射在时间分布上的3种孕震模式为主震、前震—主震—余震和群震型,并在此基础上提出了采用微震监测进行岩爆预警,并通过微震活动常用参数进行岩爆判别。基于牛顿定律的二体相互作用理论能合理地解释岩爆发生机理。岩爆发生具有前兆性,表现为岩石的声发射率与损伤变量具有一致性,在时间分布上可以归纳为三种孕震模式。深入开展岩石与其周围环境的相互作用问题研究,对于岩爆机理的研究具有重要的指导意义。
The social economy has been developing substainedly and stably for decades in China.As a result of the sharply increasing desire for better living conditions,the construction in Underground Engineering will play an irreplaceable role in future infrastructure development.However,the problems in rockburst prediction is still not solved,even the definition and mechanism of rockburst is controversal.Because of the hardships in earthquake prediction,most specialists of rock engineering take the view that rockburst can only be alarmed rather than be predicted.This paper describes a comprehensive definition of rock burst.And two-part interaction theory,based on Newton's laws,is chosen to explain the mechanism of rockburst.Two-part interaction theory is regarded as the most reasonable theory compared with other mainstream rockburst theories.Moreover,there must be some precursors before rockburst happens,for example,the acoustic emission rate agrees with the rock damage variable.Three different seismogenic models,based on different time distributions,are summarized to guide the design and construction of underground works.
