摘要
结合资料收集、地质调绘、物探、地质钻探及孔内有害气体测试等综合勘察手段,查明了沪渝蓉高铁大别山区域某隧道有害气体的成因、类型、分布特征、含量;指出该隧道内一氧化碳最大浓度超过规范中的限值,其他有害气体虽然未超过限值,但同样需要关注;分析有害气体的成因、运移及储存机制,划分各有害气体的危险性等级,可为该区域新建隧道工程有害气体的勘察提供参考。
Combines comprehensive survey methods such as data collection,geological mapping,geophysical prospecting,geological drilling and harmful gas testing in boreholes to identify the origin,type,distribution characteristics,and content of harmful gases in a tunnel in the Dabie Mountain area of the Huyurong high speed railway.It is pointed out that the maximum concentration of carbon monoxide in the tunnel exceeded the limit in specifications,although other harmful gases do not exceed the limit,attention should also be paid to them.The causes,migration,and storage mechanisms of harmful gases are analyzed,the hazard levels of each harmful gas is classified,it can provide reference for the survey of new tunnel projects in this area.
