摘　　要：受自重应力影响,深埋隧道往往存在高地应力,岩爆是其开挖过程中常见的地质五灾害之一。影响岩爆的因素众多,一般认为与地质构造、地应力大小、围岩岩性、隧道埋深及施工条件等有关,需要综合多种因素共同考虑。总结已有研究,可将岩爆影响因素分为两类:一是岩石内部影响因素,二是岩石外部影响因素。结合岩爆案例及文献资料,本文归纳分析了影响岩爆的主要因素和特征,提出了相应的防治措施,为深入开展深埋隧道的岩爆孕灾机理、预测预警和防治措施研究提供了参考。Affected by self-weight stress,deep-buried tunnels often have high in-situ stress,and rockburst is one of the five common geological disasters in the excavation process.There are many factors affecting rockburst,which are generally considered to be related to geological structure,in-situ stress,surrounding rock lithology,tunnel burial depth and construction conditions,etc.,and multiple factors need to be considered together.Summarizing the existing researches,rockburst influencing factors can be divided into two categories:one is the internal influence factors of the rock,and the other is the external influence factors of the rock.Based on rockburst cases and literature data,the main factors and characteristics of influencing rockburst are summarized and analyzed in this paper,corresponding prevention measures are put forward,which can provide reference for in-depth research on the mechanism of rockburst disaster,prediction and early warning and prevention measures in deep buried tunnels.
