航站楼火灾场景下的人员疏散仿真研究

机场航站楼结构复杂，发生火灾时极易对人员的生命财产安全造成威胁。为直观了解航站楼中不同位置发生火灾时产生的烟雾对人员疏散的影响，建立航站楼到达厅与夹层通道的火灾模型与人员疏散模型，分析3种不同火源情况下各关键位置烟气的温度、CO浓度和减光系数与疏散情况。结果表明，行李转盘区与夹层通道发生火灾时烟气会弥漫整个夹层通道，影响疏散安全。在航站楼现有建筑结构下，到达口联动开启可有效缩短人员疏散时间。

Simulation Study of Personnel Evacuation under Fire Scenario in Airport Terminal

The complex structure of the airport terminal building poses a threat to the life and property of people in case of fire. In order to visualize the impact of smoke on evacuation in different locations in the terminal building, a fire model was developed for the arrival hall and mezzanine passageway of the terminal building to analyze the temperature, CO concentration and light reduction coefficient of smoke at each key location under three different fire sources. Evacuation simulations were conducted for the arrival area of the terminal building to analyze the evacuation situation of each key location under different fire sources. The results show that among the different types of fires in the terminal building, there are areas where both the mezzanine passageway and the arrival hall are not safely evacuated in case of fire in the baggage carousel area.Smoke will fill the whole mezzanine passageway in case of fire in the mezzanine passageway, which makes evacuation of people dangerous.The stores in the arrival hall can be safely evacuated in case of fire. Under the existing building structure of the terminal building, the arrival gates can be opened to shorten the evacuation time effectively.
