为研究公路隧道火灾事故的发生规律，通过对2000—2015年我国隧道火灾事故的统计分析，获得公路隧道火灾事故发生的原因、特点和产生的后果，以及隧道火灾的发生频率、车辆分布、时间分布和地区分布等规律特征。结果表明： 车辆自身故障是诱发隧道火灾的主要因素，约占总数的63%； 火灾造成人员伤亡的事故占16.3%，造成隧道结构受损的事故占24.8%，后果较为严重； 货车是引起火灾的主要车型； 夏季和冬季是火灾的频发季节，且年平均月分布呈现“W”形分布规律； 山区及经济发达地区火灾次数相对较多。最后基于统计结果提出进一步减少隧道火灾事故的针对性建议，指出今后防火减灾对策的研究方向。

The causes, characteristics and consequences and the rules of frequency, vehicle types, time and regional distribution of fire accidents in highway tunnel are obtained by statistically analyzing the tunnel fire accidents in China from 2000 to 2015. The analytical results indicate that: 1) The fault of vehicle was the main factor for fire accident in tunnel, and it takes 63% of total fire accidents. 2) The fire, causes casualties accident, takes 16.3% of total fire accidents; and that, causes damage of tunnel structure, takes 24.8% of total fire accidents. 3) The truck was the main cause of fire. 4) Summer and winter were fire prone seasons, and the annual fire distribution presented a “W” shape. 5) There were more fire accidents in mountain areas and economically developed areas. Finally,some suggestions for further reduction of fire accidents in tunnel are presented based on the statistical results; and the future research directions of fire prevention and disaster reduction countermeasures are pointed out.
