摘　　要：随着工程建设的不断深入,铁路瓦斯隧道的瓦斯防护问题日益突出,现行规范及规定中关于瓦斯设防结构体系建设方面的不足也逐步显现,因此开展瓦斯设防体系构建方面的研究对系统性解决瓦斯防护问题具有重大现实意义。文章以铁路、公路相关规范中,瓦斯的设防要求研究为切入点,梳理其设防思路,解剖其设防结构体系,分析其存在的不足之处。并结合已建成瓦斯隧道瓦斯设防体系的实际功能和经验教训,总结确定了影响瓦斯隧道运营安全的关键因素,提出了瓦斯隧道的处理原则及构建原则,明确了瓦斯设防结构体系组织部分,对构建完备的铁路瓦斯隧道防护体系具有重大的指导意义。With the continuous deepening of engineering construction,the gas protection problems of railway gas tunnels have become increasingly prominent.The shortcomings of the current codes and regulations concerning the construction of gas fortification structural systems are also gradually emerging.Therefore,the research on the construction of gas fortification systems has great practical significance to solve the problem of gas protection systematically.Based on the research on the fortification requirements of gas in the railway and highway codes,this paper does up the thinking of gas fortification,dissects the gas fortification structure system and analyzes its deficiencies.And then combined with of the practical functions,experience and lessons learned of the gas fortification system of the completed gas tunnel,the key factors influencing the operation safety of gas tunnels are summarized,the treatment principles and construction principles of gas tunnels are put forward,and the organizational part of gas fortification structure system is clarified,which has great guiding significance for building a complete railway gas tunnel protection system.
