摘要:
为研究地铁换乘站火灾排烟及人员疏散路径，采用数值模拟方法建立地铁火灾和疏散模型，选取西安市小寨地铁换乘站作为研究对象，模拟站台层火灾烟气移动，探讨不同工况下的烟气扩散和行人疏散，并对通风排烟系统和疏散路径进行优化。研究结果表明：通过优化排烟口高度和防烟分区划分，以及设置最优疏散路径，可将地铁火灾时的疏散效率提升5.9%。即合理的通风排烟措施可有效降低火灾温度和CO体积分数，提高安全指数。研究结果可为优化地铁换乘站应急安全管理提供参考。
Abstract:
To study the smoke exhaust and personnel evacuation paths in the subway transfer station fires,a model of subway fire and evacuation was established using the numerical simulation method.Taking Xiaozhai subway transfer station in Xi’an as the research object,the fire smoke movement in the platform layer was simulated.The smoke diffusion and pedestrian evacuation under different working conditions were discussed,and the ventilation and smoke exhaust system and evacuation paths were optimized.The results show that by optimizing the height of smoke vents and the division of smoke zones,as well as setting the optimal evacuation path,the evacuation efficiency in subway fires can be increased by 5.9%.Namely,the reasonable ventilation and smoke exhaust measures can effectively reduce the fire temperature and CO volume fraction,and improve the safety index.The research results can provide reference for optimizing the emergency and safety management of subway transfer stations.
