摘要
剧院类建筑的内部空间高大、火灾荷载大、人员密度大,极大增加了火灾救援及人员安全疏散的难度,因此,合理设计剧院类建筑防排烟方式,有效控制烟气扩散和蔓延,具有重要的工程意义。基于某大剧院观众厅的实际情况,设置两种不同火源位置及相应排烟风机的启动方式,采用火灾动力学模拟软件(FDS)对观众厅的各火灾场景进行模拟计算,得到各火灾场景的控烟效果,通过对比分析确定较好的控烟方式,为工程防火提供指导性借鉴。
Because of the big internal space, large fire load, high personnel density of theatre buildings, it is very difficult to carry out fire rescue and personnel evacuation. Therefore, a reasonable design of the smoke exhaust mode of theatre buildings, effective control of smoke diffusion and spreading plays a significant role in engineering. Based on the actual situation of the auditoriums of a big theatre building, a scenario of two different dangerous locations of fire source and corresponding exhaust fan starting modes has been set up in Fire dynamics simulation software （FDS） where the fire scene of each auditorium has been simulated. The effect of smoke control in each fire scene has been obtained and compared in order to find out a better way to control fire smoke, and provide guidance for fire preven- tion engineering.
