摘　　要：针对城市火灾事故中大型公共场所外人员疏散难的问题,在考虑影响火灾应急疏散因素的基础上,分析火灾应急疏散的模型,并以某市体育馆周边道路情况为例,采用Dijkstra算法和区间数网络算法对影响交通道路网的因素进行综合优化,分析得到最短路径和最小风险路径。结果表明:该模型的应用可实现三维场景中火灾应急疏散路径的可视化,可为火灾应急疏散提供决策支持。According to the difficult problem of evacuations outside the large public places in city fire accidents, considering the impact of urban fire emergency evacuation on the basis of factors, analyze the fire emergency evacuation model. And taking as some gymnasium nearby situation as example, use Dijkstra algorithm and interval number network algorithm to comprehensively optimize factors that affect the transportation network. Acquire the shortest path and minimum danger path. The result shows that the application of model can realize the visualization of fire emergency evacuation path in 3D scene and provide decision support for fire accident emergency evacuation.
