摘要
采用事故树分析(FTA)与层次分析(AHP)相结合的方法对动车组列车火灾风险进行分析,并求得各指标层对目标层的影响权重,同时还将单独的FTA方法与FTA-AHP方法进行了比较,总结出FTA-AHP方法的优点,解决了在动车组列车火灾风险分析中的什么是重点的问题。结果表明:对动车组列车火灾风险影响较大的因素依次为,列车材料耐火等级、火灾报警系统、防火巡查、电气系统的安全状况、消防设施的维护等,必须首先从这些因素入手来控制动车组列车火灾风险。
The fire risk of electric muhiple unit （EMU） train is analyzed by using the methods of fault tree analysis （FTA） and analytic hierarchy process （AHP）, and the influence weight of each index layer on target layer is obtained. Further, the paper, through a comparison between the FTA method and the FTA-AHP method, summarizes the advantages of the latter and identifies the key problem of the train fire risk analysis in EMU train. The results show that the factors influencing the fire risk of EMU train are fire-protection rating of train material, fire alarm system, fire prevention patrol, safety status of electrical systems, and maintenance of fire fighting facilities etc. Therefore, those above-mentioned factors should be given priority in controlling the risk of EMU train fire.
