Abstract: Prevention of fire accident is one the key points in metro station emergency management. Based on the secondary development technology of building information modeling （BIM），the material information in BIM model can be extracted effectively，quickly and accurately，thus the data transmission problem between BIM and Pyrosim software is solved. On this basis，BIM is integrated into Pyrosim software to achieve the BIMbased fire simulation，the fire simulation information and the available safety evacuation time at each key position are obtained.Thus a fire simulation method based on BIM for metro station is established. Typical station fire conditions are simulated and verified，the results show that the research method can give better play to the advantages of BIM technology.
