【摘要】 本文探讨了火灾烟雾对城市轨道交通安全疏散系统设计的影响。以双层岛式地铁车站作为模拟对象,使用PyroSim作为模拟工具,在地下二层的站台层设置面积为1m2的正方形火源,讨论增加通风口的必要性。模拟结果表明,在有通风口的情况下,地铁火灾烟气扩散速度大大降低,为乘客争取了更多的逃生时间。更多还原

【Abstract】 This paper discussed the impact of fire smoke on the design of urban rail transit safety evacuation systems.Taking a double-decked island subway station as a simulation object, using PyroSim as a simulation tool, a square fire source with an area of 1 m2 was set on the platform floor of the second basement to discuss the necessity of adding vents. The simulation results showed that in the case of vents, the subway fire smoke diffusion rate was greatly reduced, and more escape time was obtained for passengers.更多还原
