摘　　要：为了通过虚拟疏散训练手段提高人员火灾疏散能力,提出基于数值模拟的烟气可视化方法和烟气危害综合评价模型。以Open Scene Graph(OSG)作为疏散系统的虚拟现实平台,根据FDS模拟结果,采用粒子系统网格在OSG中实现烟气蔓延效果。在此基础上开发了虚拟疏散训练系统,并应用于某宿舍楼。火灾虚拟疏散系统可以帮助学员体验真实的火灾场景,并且通过虚拟训练逐渐发现最安全的疏散路径。In order to improve the fire evacuation ability of people by virtual evacuation trainings, a visualization method of smoke based on fire numerical simulations and an integrated evaluation model of smoke hazards were proposed. Taking the Open Scene Graph （OSG） as virtual reality platform of evacuation system, a visualization method of smoke was realized in OSG by particle system grids based on the results of FDS. A virtual evacuation train ing system was developed and applied in a six-story dormitory. The results indicated that people can experience the realistic smoke and gradually find the safest evacuation path by the virtual trainings.
