| 摘 要： | 运用区域模型模拟车站内不同防排烟工况下烟气温度、高度、CO体积分数随时间的变化规律,以三项危险临界条件是否实现作为衡量防排烟效果的判据.模拟结果表明,只有同时对站台楼梯送风防烟和对火源所在防烟分区及时排烟,才能在车站内实现最有利于人员疏散的安全环境.

| Abstract: | By using a zone model, simulates the behaviour of smoke temperature, height, volume fraction of CO changing with time under different smoke control and extraction conditions in the station and introduces three critical conditions as a criterion for judging the effects of different smoke control and extraction methods. The results show that only supplying air to platform stairs and simultaneously extracting smoke of fire zone can a best safe evacuation environment in the station be maintained. |
