摘要
为明确高层建筑火灾致因因素,通过运用事故树理论来分析高层建筑火灾。首先,根据事故树理论方法构建事故树,在构建事故树过程中对寻找到的基础事件进行因素分类,将其分为个人因素和组织因素;其次,通过对事故树中的逻辑关系进行布尔代数运算,找出最小割集和最小径集,通过计算出的最小割集和最小径集进行结构重要度计算,以确定在其模型结构中的重要程度;最后,将重要程度与其因素种类进行对应,找出在火灾中造成更大影响的因素种类,并结合实例进行分析。结果表明,事故树方法可以准确找出高层建筑火灾中造成更大影响的因素种类并得出科学有效的预防措施,为高层建筑火灾的安全管理和事故预防提供新的分析思路和参考。
In order to clarify the cause factors of high-rise building fire,the theory of fault tree analysis is used to analyze high-rise building fire.Firstly,the fault tree analysis is constructed according to the accident tree theory method.In the process of building the fault tree,the factors of the foundational events are classified into individual factors and organizational factors.Secondly,the minimum cut set and minimum path set are found out through Boolean algebra operations on the logical relations in the fault tree,and the structural importance is calculated through the calculated minimum cut set and minimum path set.In order to determine the importance degree in the model structure,at last,the importance degree is mapped with the types of factors,and the types of factors that cause greater impact in the fire are found out,and the analysis is combined with examples.The results show that the fault tree analysis method can accurately find out the more influential factors in high-rise building fire and get scientific and effective preventive measures,which provides a new analysis and reference for high-rise building fire safety management and accident prevention.
