摘　　要：铁路瓦斯隧道施工工区的瓦斯等级,是根据该工区的瓦斯涌出量来确定的。目前,铁路规范中关于瓦斯涌出量的计算方法主要适用于煤矿巷道瓦斯涌出量的计算,不太适用铁路隧道瓦斯涌出量的计算。文章旨在铁路规范有关瓦斯涌出量计算方法的基础上,提出更适用铁路隧道瓦斯涌出量计算的方法,以便有利于提高勘察设计阶段确定隧道瓦斯等级的准确性。The gas class of the constructed area of railway gas tunnels is settled in accordance with the gas emission amount in the area.At present, the calculating methods of gas emission amount in the railway specifications are mainly applied to calculate the gas emission amount in roadways of coal mines rather than that in railway tunnels.This thesis aimed to put forward methods that are more applicable in calculation of gas emission amount in railway tunnels based on the relevant calculating methods in railway specifications , so as to improve the accuracy of the settlement of the gas class in tunnels in the phase of inspection and design.
