BIM-based Fire Hazard Simulation of Metro Station
North China University of Water Resources and Electric Power, Zhengzhou 450046, China |
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.
