KTV受限空间火灾及人员疏散模拟

Simulation on a KTV fire and people evacuation

使用FDS软件和BuildingExodus软件,对某KTV场所中的火灾和人群疏散情况进行模拟。FDS模拟得出KTV各区域内热辐射温度、烟气可见度、有毒有害气体浓度达到危险极限的时间,确定火灾的可用安全疏散时间。通过Build-ingExodus建立人群疏散模型,分析人员疏散时间、疏散距离、堵塞等待时间及各出口使用情况等,得出人员必需安全疏散时间(RSET)。通过对比发现,人员在现有设计下火灾时可以安全疏散。

FDS and Buildingexodus were used to simulate a KTV fire and people evacuation. By FDS, the critical time of temperature, visibility, concentration of hazardous gas was obtained, and then the available safety evacuation time was identified. People evacuation model was founded by Buildingexodus, the people evacuation time, evacuation distance, obstruction time and use of exits were analyzed, and then required safety evaeua tion time was obtained. By comparison, it was proved that peo- ple could be evacuated safely.
