摘要
当地铁区间隧道中的列车中部着火且着火部位正好处于联络通道附近时,根据就近排烟的原则,可以利用联络通道就近将火灾烟气排入未着火隧道中,使乘客能在无烟的环境下沿隧道顺利疏散至前方或后方车站。文章利用FDS(Fire Dynamics Simulator)数值模拟软件对全尺寸地铁区间隧道利用联络通道排烟的效果进行数值模拟并对模拟结果进行分析,得出了使用联络通道排烟的最佳送风速度、排烟速度。文章为地铁区间隧道火灾的防治提供参考。
When the central train in the subway tunnel on fire and the fire place just at the contact channel, according to the principle of proximity smoke evacuation, the fire smoke can be discharged into the tunnel which is not on fire by the contact channel to make the passengers successfully evacuate to the front or rear station along the tunnel in the smoke-free environment. This paper takes the numerical modeling for the effort of full-scale subway tunnel using contact channel to discharge smoke by FDS numerical simulation software, and it obtains the best air supply velocity and smoke evacuation velocity of using the contact channel to discharge smoke. It also provides references to the prevention and control of the fire in subway tunnel.
