摘要
基于系统安全分析方法并结合数理统计理论,系统地分析了近年重大火灾隧道存在的问题,建立了隧道消防安全系统原理图及评估指标体系,运用多元统计理论中的主成分分析法,构造了一种基于统计基础上的综合评估函数,对近年来的典型火灾隧道的防火安全系统进行了合理评估,并针对评估结果构造了分级标准,给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,能全面系统地反映隧道消防安全系统状况,及时发现隐患,采取消防控制措施,减少火灾的潜在危险。
The existent problems of tunnels which had occurred momentous fire are analyzed based on safety system analysis and combined with tunnel fire statistic. The principle block diagram and assessment indexes system of fire fighting safety system in tunnel are founded, and synthetic assessment function grounded on statistic by using multi-elements is established. The fire fighting safety systems of typical tunnels are evaluated reasonably, and grade criterion is formatted by its results. The assessment of the example in Xuefeng Mountain Tunnel shows that this method can well evaluate the status of fire fighting safety system in tunnel, so that the fire precautions may be accurately adopted, and the serious potential risk may be avoided.
