摘要
隧道岩爆是硬岩隧道地质问题之一,岩爆处治是否成功,直接关系到隧道施工安全及施工质量,岩爆特征也因地区而异,为此,依托西南地区隧道施工,对隧道岩爆处治技术进行研究,分析总结了隧道施工阶段岩爆典型特征,针对岩爆实际发生的部位、频率、爆坑深度及范围,采取了一系列对应的处治措施,经施工实际检验,处治措施合理、有效、针对性强,保障了施工人员及施工机械设备的安全,实现了施工安全、质量及施工进度的全面控制,颇具推广价值。
Tunnel rock burst is one of the geological problems in hard rock tunnels.The success of rock burst treatment directly affects the safety and quality of tunnel construction,and the characteristics of rock burst also vary from region to region.Therefore,based on the construction of tunnel rock bursts in the southwest region,the treatment technology of tunnel rock burst is studied,and typical characteristics of rock burst during tunnel construction are analyzed and summarized.The actual location,frequency,depth and scope of rock burst occurrence are analyzed and summarized,A series of corresponding treatment measures have been taken.After actual construction inspection,the treatment measures are reasonable,effective,and highly targeted,ensuring the safety of construction personnel and construction machinery and equipment,and achieving comprehensive control of construction safety,quality,and progress,which is of great promotion value.
