| 摘 要： | 特长公路隧道发生火灾,扑救困难,易造成严重损失,是影响隧道安全运营的一个关键因素。借助大比例火灾模型试验,系统研究了火灾时隧道内温度随时间的变化,最高温度与通风风速、火灾规模的关系,提出了火灾阶段划分和隧道火灾的预防救援措施,并将研究成果应用于18 km长的秦岭终南山特长公路隧道防灾工程。

| Abstract: | Fire in a very long highway tunnel is difficult to put out and may cause serious damage,and thus serves as one of the key factors in operation safety.Based on a large-scale fire model testing,the following aspects are studied systemically:the process of temperature variation with time,and the relationships between maximum temperature,air velocity and intensity of fire sources.Partitions of fire phases and prevention-rescue measures are proposed.The achievements are applied to the hazard prevention project of the Qinling highway tunnel,the second longest road tunnel of the world. |
