摘要:
为了研究取消轨顶风口对地铁地下车站火灾防排烟的影响，采用CFD方法，针对全封闭站台门系统和全高站台门系统2种典型地铁车站，模拟车站公共区火灾和车站列车火灾发生时，有无轨顶风口对车站内排烟效果的影响。研究结果表明：针对车站公共区火灾，无论是全封闭站台门还是全高站台门系统，取消轨顶排烟口对公共区烟气温度、可见度、CO浓度等影响较低；但针对车站列车火灾，取消轨顶排烟口对公共区烟气温度、可见度、CO浓度均具有较大影响，排烟效果下降较多。
Abstract:
In order to study the influence of removing the vent at rail top on the smoke control of fire in the underground station of subway, aiming at two kinds of typical subway stations with the fullyenclosed platform door system and the fullheight platform door system respectively, the influence of with or without the vent at rail top on the smoke exhaust effect in the station when the fire occurred at the public area and train of the station was simulated by using the CFD method. The results showed that for the fire at the public are of the station, the influence of removing the smoke vent at rail top on the smoke temperature, visibility and CO concentration in the public area was relatively low when adopting whether the fullyenclosed platform door system or the fullheight platform door system. However, for the train fire of the station, the influence of removing the smoke vent at rail top on the smoke temperature, visibility and CO concentration in the public area was relatively great, and the smoke exhaust effect reduced obviously.
