摘要
预防火灾事故是地铁车站应急管理的重点之一。基于BIM(建筑信息模型)的二次开发技术,实现了对BIM中材质信息的有效、快速、准确的提取,解决了BIM和Pyrosim软件间的数据传输关键问题。在此基础上,将BIM集成在Pyrosim软件,实现了基于BIM的火灾模拟,得到了火灾模拟信息和以及关键位置的可用安全疏散时间,从而建立了一套基于BIM的地铁车站火灾模拟仿真方法。仿真模拟验证表明,该方法能较好地发挥BIM的优越性。
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 extract-ed effectively,quickly and accurately,thus the data transmis-sion 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 in-formation 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 con-ditions are simulated and verified,the results show that the re-search method can give better play to the advantages of BIM technology.
