摘　　要：随着我国隧道建设规模和建设速度不断提升,隧道修建的深度、长度及地质条件复杂程度也随之增加,高地应力岩爆是隧道安全施工面临的重大隐患,合理的岩爆防控技术是保证隧道安全快速穿越岩爆段的关键所在。本文依托锦屏水电站辅助洞工程,通过文献调研和统计分析等方法,研究了岩爆发生的时间和空间特征,分析了现场岩爆段施工分级防控措施,介绍了锦屏辅助洞岩爆治理的成功经验。研究成果可为同类工程的施工提供技术资料和经验借鉴。With the continuous improvement of the scale and speed of construction of tunnels in China,the depth,length,and complexity of geological conditions of tunnel construction also increase.High geostress rockburst is a major hidden danger in the safe construction of tunnels.Reasonable rockburst prevention and control technology is the key to ensuring the safe and rapid tunneling in rockburst sections.With the auxiliary tunnel work of Jinping Hydropower Station as a case for study,this paper studied the temporal and spatial characteristics of rock burst through literature investigation and statistical analysis,analyzed the hierarchical prevention and control measures of tunneling in rock burst section and introduced the success of rock burst control in Jinping auxiliary tunnel.The conclusions can provide technical data and references for similar projects.
