摘　　要：基于系统安全分析方法并结合数理统计理论,建立了隧道消防安全系统原理图及评估指标体系,构造了一种基于统计基础上的综合评估函数,提出了公路隧道消防安全等级评估的新思路。以雪峰山隧道的实例计算表明,该评估模型具有简便性、可操作性和准确性,能全面地反映隧道消防安全系统状况,以便及时发现隐患,减少火灾的潜在危险。Based on safety system analysis and tunnel fire statistic theory, the principle block diagram and assessment index system of fire safety system of tunnels are worked out and comprehensive assessment function based on statistics is established. The new idea for highway tunnel fire safety level assessment is put forward. A case assessment of the Xuefeng mountain tunnel shows that this method is simplicity, feasibility and accuracy and can well evaluate the status of fire safety system of tunnel. So, the hidden risk of fire can be found timely and potential risk would be reduced.
