着火区域内温度及烟气层高度对被困人员的逃生具有重大的影响。运用CFAST软件对某机场一层一楼远离楼梯口的一个房间进行模拟,通过设置三种工况,得出温度、烟气层高度随时间变化的火灾参数,对比不同工况下温度、烟气层随时间的变化情况,为火场受困人员疏散、单位及公安消防部门处置预案制定以及为建筑的防火性能化设计提供部分技术参考。 The temperature and the height of flue gas in the fire area have a significant impact on the escape of trapped persons. Using CFAST software to simulate a room on the first floor of an airport far away from the stairway, set up three working conditions to get the fire parameters of temperature and flue gas level with time, compare the temperature, flue gas Layer changes over time, evacuation of people trapped in the fire field, the unit and the public security fire department plan for the preparation of disposal and fire performance for the design of the building to provide some technical reference.
