摘要
为辅助隧道火灾风险管理及决策,提出隧道火灾社会风险可接受标准定义和制定原则;比较国外隧道风险相关标准,统计分析我国2000-2020 年间隧道火灾死亡事故案例,开展社会公众隧道火灾风险认知调查;基于F/N曲线方法,建立适用于我国的隧道火灾社会风险可接受标准,明确事故频率和后果的可接受临界阈值.结果表明:公众对于隧道火灾事故风险现状持可容忍态度;我国隧道火灾死亡事故最大可接受频率设定为10-5/(km·a),最大可容忍频率设定为10-4/(km·a).
Abstract
In order to assist tunnel fire risk management and decision-making,the definition and principles of social risk acceptance criteria for road tunnel fire were established.Based on a statistical analysis of tunnel fire fatalities in China from 2000 to 2020 and a survey of public perceptions of tunnel fire risk,social risk acceptance criteria of tunnel fires in China was developed by the F/N curve method,and the acceptance critical limits for accident frequency and consequences were defined.The results show that the public has a tolerable attitude towards the current situation of tunnel fire accident risk.The maximum acceptable frequency of tunnel fire fatalities in China is set at 10-5/(km·a),and the maximum tolerable frequency is set at 10-4/(km·a).
