以某市展览馆为研究对象,该展览馆顶棚采用钢结构,存在防火分区面积过大和局部疏散距离过长的消防安全问题。本文采用火灾模拟软件FDS和人员疏散软件Pathfinder对某展览馆进行了火灾风险评估。模拟结果显示,在智能水炮系统和排烟系统均失效时,展览馆内人员疏散的安全性无法得到保证。在综合模拟结果与该展览馆现有消防设施的基础上,提出了加强消防安全的建议。
With the exhibition hall of a city as the research object, the steel structure of the exhibition hall ceiling has the fire safety problems that the area of the fire prevention partition is too large and the distance of the local evacuation is too long. In this paper, a fire risk assessment of a museum was conducted using fire simulation software FDS and personnel evacuation software Pathfinder. The simulation results show that the safety of personnel evacuation in the exhibition hall can not be guaranteed when both the intelligent water-gun system and the smoke exhaust system fail. On the basis of the comprehensive simulation results and the existing fire facilities in the exhibition hall, suggestions for strengthening fire safety are put forward.
