摘要:随着城市化建设的快速推进，地铁迅速且大量地在城市中投入使用。地铁客运量大、客流量大、空间封闭的特点，给应急管理带来巨大的挑战，特别是火灾应急管理。本文对郑州货栈街地铁车站进行Revit建模，将Revit中导出的DXF文件导入Pyrosim软件进行火灾烟气模拟、火灾设定切面温度模拟、能见度模拟、火源烟雾探测模拟、火灾燃烧模拟，根据模拟结果，进行数据分析，得出地铁车站关键节点的最大疏散时间。基于BIM技术+Pyrosim对地铁火灾全过程进行预演以及对相关指标进行分析，为地铁车站的设计和消防设施的布置以及火灾发生时的应急处置提供了依据。同时本文对BIM技术与专业火灾模拟软件的结合进行了理论探索与实例验证，表明将BIM技术的数据共享及仿真预演的优势向火灾模拟方向赋能，是具有潜力的。

Abstract: With the rapid urbanization process, subways have been increasingly put into usage in many cities. The large load capacities, the large ridership and the closed space of subway is bringing great challenges in emergency management especially in fire emergency management. In this paper, a BIM model of Zhengzhou Huozhan street metro station was built by using Revit, and then import the DXF files into Pyrosim software to conduct fire smoke simulation, set-plane temperature simulation, visibility simulation, fire source smoke detection simulation and fire combustion simulation. Fire hazard simulation based on BIM and Pyrosim can be used to rehearse the entire process of subway fire evacuation and to analyze the relevant indicators, which could provide the guidance for metro station design and fire-fighting equipment′s layout, as well as the emergency measures in the case of fire hazard. Meanwhile, this paper has explored the combination of BIM technology and professional fire hazard simulation software in a theorical way, which verified with examples and indicated that applying those advanced BIM technologies in data sharing and rehearsal simulation is having great potentials.
