摘要
对引起高层建筑火灾的因素进行系统分析,建立以高层建筑火灾为顶上事件的事故树,并进行事故树分析,得到影响顶上事件的最小割集.利用布尔代数计算方法,计算了基本事件的结构重要度系数、概率重要度系数和临界重要度系数,确定了影响高层建筑火灾的主要因素,针对提高高层建筑的消防安全性,提出了相应的防控措施,并从安全系统工程角度提供了高层建筑火灾防控研究的建议.
The affecting factors of fire accidents for high-rise buildings were analyzed. By defining high- building fire accidents as the top event, a {ault tree was established and analyzed, the minimal cut sets affecting the top event were achieved. Using Boolean algebra calculation method, coefficients of structural importance degree,probability importance degree and pivotal importance degree of basic event were calculated, the main factors of fire accident for high-rise building were determined. Finally, corresponding measures to improve the prevention of high-rise building fire accidents were put forward and suggestions were provided from the safety system engineering for researches on high-rise building fire accidents.
