摘　　要：防火救灾已成为公路隧道防灾减灾的重点工作,通过引入安全系统工程中的事故树分析法,建立公路隧道火灾事故树,从最小割集、最小径集和结构重要度3方面,找出公路隧道火灾的主要成因,并由此提出公路隧道防火救灾对策。实例分析表明,事故树分析法能够对引发公路隧道火灾的各种因素及其逻辑关系作出系统、全面的阐述,并能为公路隧道防火安全提供真实、可靠的依据。Firefighting has become a major task of prevention and relief of disasters in highway tunnel. This paper establishes fire event tree for highway tunnel by adoption of the event tree analysis method in safety system project, and fnds out main causes of fire in highway tunnel from three aspects, i.e. minimal cut set, minimal radial set and structural importance, and proposes countermeasures for firefighting in highway tunnel accordingly. The analysis of examples shows that the event tree analysis method can systematically and entirely expatiates all kinds of causes triggering fire in highway tunnel and their logic relations and can provide true and reliable bases for firefighting safety of highway tunnel.
