Research On Fire In Subway Station Based On BIM

As the highest efficiency city transport transport in solving urban traffic problems, the number of fires in the subway station gradually increased, causing heavy casualties and huge economic losses. Building Information Modeling(BIM) is a new technology in recent years in the field of computer-aided architectural design, which is based on the relevant information and data as a basis for building projects model, the establishment of a complete, highly integrated building works project Information model. With BIM technology subway station fires simulation can be a true representation of the fire when the fire broke out as well as the evacuation route, and for different fire emergency plans, provide a theoretical basis and reference for fire fighting and evacuation command.This paper will focuses on the subway station fire evacuation simulation theory and simulation theory, introduced the development of numerical simulation of fire technology and BIM technology, as well as the results of other works made for the subway station in the evacuation and fire simulation technology combined with BIM offers possibilities and technical support. Then a subway station CAD drawings based on three-dimensional modeling with BIM-based modeling software, while the experimental design subway station fire, use Pyrosim BIM software based on the model of the subway fire accident simulation, analysis subway fire a variety of factors caused the event, which can verify the necessity of research and optimization of the safety of the subway station, to provide the basis for the later study. Combined with Pathfinder software to analyze the effects of different positions and different power fire on fire evacuation, to make reasonable suggestions for optimization settings platform structure. Integrated subway station fire simulation results and evacuation simulation results, the subway station to enhance fire safety measures to accelerate the feasibility of safe evacuation.In this paper, FDS, combined with BIM technology for the subway station fire simulation studies and the safety of personnel evacuation simulation study of the subway station fire safety were assessed, as well as the use of BIM model provides a new way.In this paper, BIM technology, combined with FDS conducted subway station fire simulation studies and simulation of personnel escape, subway station fire safety were assessed and proposed metro station enhance fire safety measures, as well as the use of BIM model provides a new way.
