摘　　要：瓦斯地区隧道开挖过程中存在瓦斯爆炸和瓦斯突出的危险,须对可能发生的危险进行预测。基于某公路隧道工程,采用层次分析法对隧道等级进行评价,并采用模糊综合评判的方法,对隧道瓦斯发生危险性的概率进行分析。结果表明:隧道所处为瓦斯区的权重值为0.390;分级评价的评分为74.89,施工过程中应按照高瓦斯隧道等级制定瓦斯灾害控制措施;通过隧道瓦斯灾害危险性综合模糊评判,确认左线隧道施工危险发生的等级为4级,且危险发生的概率较大,有可能发生瓦斯灾害。There is danger of gas explosion and gas outburst in the process of tunnel excavation in gas area,and the possible danger should be predicted.Based on a highway tunnel project,AHP is used to evaluate the tunnel grade,and fuzzy comprehensive evaluation method is used to analyze the probability of tunnel gas risk.The results show that the maximum weight value of the tunnel is 0.390.The rating of classification evaluation is 74.89.The gas disaster control measures should be formulated according to the grade of high gas tunnel during construction.Through the fuzzy comprehensive evaluation of tunnel gas disaster risk,it is confirmed that the construction risk of the left line tunnel is level 4,with larger probability of danger,and a gas disaster may happen possibly here.
