摘　　要：成都轨道交通18号线工程土建5标龙泉山隧道是目前国内地铁工程中最长、采用矿山法施工的瓦斯隧道。作为典型的油气田区高瓦斯隧道,其工程地质条件复杂、施工风险大,要求标准高。结合工程实际,阐述了地铁瓦斯隧道施工所采取的进洞管理措施、超前地质预报、施工通风、信息化施工、瓦斯异常处理等综合管控措施,可供类似工程参考。Longquanshan Tunnel,Civil Work Bid 5 of Chengdu Metro Line 18,is currently the longest gas tunnel in China which mining method has been applied.As a typical high gas tunnel passing through oil-gas field,the geological conditions of this project are complex with high construction risks and high requirements.Combining with project practice,this paper discusses the comprehensive control measures of security check management at tunnel entrance,advance geological forecast,construction ventilation,informatization construction,gas abnormal treatment and etc.which may give references to the similar projects.
