摘　　要：在总结分析近30年典型大中型公路隧道火灾案例基础上,给出了大中型隧道火灾主要起因统计,根据隧道火灾起因和故障树(FTA)分析原理,建立了隧道火灾起因故障树,通过计算故障树各基本事件发生的概率,计算出各基本事件关键重要度并进行排序,找出了导致隧道火灾的常见高频原因,并提出了防范隧道火灾的措施。Based on the analysis of fires cases in large and moderate tunnels in recent 30 years, the statistics of causes of fires are presented. According to the tunnel fire causes and fault tree analysis （FTA） theory, the fault tree of causes of fires in large and moderate tunnel is established. By calculating occurrence possibility of every basic event of the fault tree, the critical importance degree of every basic event is calculated and sequenced. So the causes of high frequent tunnel fires are searched out and some preventive measures against tunnel fire are put forwarded.
