摘要/Abstract

摘要： 为合理设置长大铁路隧道群紧急救援站的防灾通风系统,采用模型试验和数值模拟的方法研究不同隧道群洞口间距(明线段长度)条件下,列车火灾烟气对相邻隧道内环境的影响,得到无需设置防灾通风系统的洞口安全距离。研究结果表明:距火源点20 m以内,列车火灾烟气对温度、可视度影响严重,50 m以外基本无影响;考虑火源蔓延车厢的长度、火灾列车安全停车距离、烟气影响范围等因素,得出隧道口紧急救援站的洞口间距(明线段长度)大于250 m时,列车火灾烟气对隧道内环境几乎无影响,可不设置防灾通风系统;该间距小于250 m时,应设置防灾通风系统。

Abstract: In order to set reasonably disaster prevention and ventilation systems for emergency rescue stations for a given long railway tunnel group from the point of view of disaster prevention and rescue, effects of train fire smoke on the environments in the adjacent tunnels were studied by means of model tests and numerical simulation. The results show that within the range of 20 m from the fire source point, the smoke has a great influence on the environmental temperature and visibility, but there is almost no effect on the region more than 50 m away from the fire source point, that when the distance between emergency rescue station and tunnel portals is greater than 250 m, the train fire smoke has almost no effect on the tunnel environment and there's no need to set a disaster prevention and ventilation system considering the length of the fire source, the fire train parking error, the influence range of the smoke and other factors, and that when the distance is not greater than 250 m, a disaster prevention and ventilation system should be set.
