基于FTA和AHP的高校宿舍火灾事故分析

Analysis of Fire Accidents in College Dormitories Based on FTA and AHP

针对高校宿舍火灾事故频发、防范工作量大的问题,为找到有效解决措施,通过结合火灾发生要素、高校宿舍特点及安全系统工程理论,利用事故树和层次分析法对高校宿舍火灾事故影响因素及其影响程度大小进行定性与定量分析。结果表明:引发高校宿舍火灾事故的原因及渠道众多,防范工作难度较大,其中电火源是导致高校宿舍火灾事故发生的主要影响因素,学生消防综合素质不高和灭火不及时是重要影响因素。该研究可为高校科学合理地开展宿舍火灾防范工作提供决策参考。

In view of the frequent occurrence of fire accidents in college dormitories and heavy prevention workload,in order to find effective solutions,by combining the factors of fire occurrence,the characteristics of college dormitories and the theory of safety system engineering,fault tree analysis and analytic hierarchy process are used to qualitatively and quantitatively analyze the influence factors and influence degree of fire accidents in college dormitories.The results show that there are many causes and channels for fire accidents in college dormitories,and that it is difficult to prevent them,among which,power supply and fire source are the main influence factors that lead to fire accidents in college dormitories,and the low comprehensive quality of students'fire protection and untimely fire extinguishing are important influence factors.This study can provide a decision-making reference for colleges and universities to carry out dormitory fire prevention work scientifically and reasonably.
