摘要
合(肥)武(汉)铁路客运专线红石岩隧道穿越大别山区,大别山区系变质岩地区,但是在隧道施工过程中发现燃烧现象,通过现场检测和化学试验确定岩石所含气体成分,在此基础上提出了相关瓦斯隧道施工技术措施,通过这些技术措施在红石岩隧道施工中的应用,确保了隧道施工的安全,并且收到了良好的效果。
Hongshiyan tunnel on Hefei - Wuhan passenger-dedicated railway crosses Dabieshan mountainous area, which consists of metamorphic rocks. However, combustion phenomena are observed during the construction of the tunnel. The composition of the gases contained in the rocks is determined by means of in-situ monitoring and chemical tests, on basis of which technological construction countermeasures are established for the gas tunnel. Due to the application of the technological construction countermeasures, the safety of the tunnel construction is guaranteed and good effects are achieved.
