公路隧道典型火灾场景风险评估研究

Risk Assessment of Typical Fire Scenes in Highway Tunnels

目前,国内外公路隧道火灾事故风险评估一般从理论层面进行分析,对隧道火灾事故缺乏分类研究及事故场景模拟分析。因此,文章收集和调查了国内外典型的公路隧道火灾事故案例,总结归纳出了4类典型的公路隧道火灾场景,并依托某大型沉管隧道工程实例,采用火灾场景模拟法确定事故损失等级,进而给出大型单车公路隧道火灾事故的风险值,以期对我国公路隧道火灾防治与应急救援管理提供参考。

At present,the risk assessment of highway tunnel fire accidents at home and abroad is generally analyzed from the theoretical level,and there is a lack of specific classification research on tunnel fire accidents and simulation reconstruction of fire accident scenes.Therefore,this paper collects and investigates domestic and international cases of road tunnel fire accidents,consolidates four typical types of road tunnel fire scenarios,and relies on a large-scale immersed tunnel project to determine the accidental loss level using a fire scenario simulation method to get risk scores of road tunnel accident caused by large single-vehicle fire.This research can provide reference for fire prevention and emergency rescue management of highway tunnels in China.
