为了提供便利的交通运输条件,世界各地修建了大量的交通隧道,而且新建隧道的长度仍在不断增加。然而,由于隧道内部空间受限,一旦发生火灾,不但燃烧产生的高温会对隧道结构造成损坏,而且,由燃烧产生的大量有毒有害气体会导致隧道内人员丧生,国内外多次发生过多起此类事故。本文主要统计分析了近年来发生在国内外的隧道火灾事故,阐述了隧道火灾的严重性及特殊性,并对国内外在隧道火灾防治方面所做工作进行了介绍,最后,对今后隧道火灾防治的研究提出了建议。
In order to provide convenient transport conditions, a large number of traffic tunnels have been built around the world, and the length of new tunnels is still increasing. However, due to the limited internal space of the tunnel, in case of fire, not only the high temperature caused by the combustion will damage the tunnel structure, but also a large amount of poisonous and harmful gas generated by combustion will result in the death of persons in the tunnel and many occurrences at home and abroad Such accidents. This paper mainly analyzes the tunnel fire accidents in recent years at home and abroad, expounds the seriousness and particularity of the tunnel fires, and introduces the domestic and international work in tunnel fire prevention and control. Finally, The research made the suggestion.
