摘要
高瓦斯长大隧道施工难度大、风险高,瓦斯防治是其工程安全管控的重中之重。结合在建重庆渝广高速公路华蓥山隧道瓦斯段落的设计与施工情况,总结高瓦斯长大隧道施工所采取的地质预报、施工通风、信息化管理以及瓦斯抽采与引排等综合处理措施,供类似工程参考。
High methane large and long tunnel construction features difficulty and high risk,methane prevention and control is most important in project safety control. This paper,with design and construction of high methane sector of Huayingshan Tunnel of Chongqing Chongqing-Guangan Expressway as example,summarized comprehensive treatment measures such as geological forecasting,construction ventilation,informatization management,methane exhaust and disposal,etc. adopted in high methane large long tunnel construction,for reference of other similar projects.
