摘　　要：建筑物发生火灾时,为获得能够帮助人员快速、安全撤离的最优疏散路径,根据建筑物内部自身火灾风险及火灾发生时产生的有毒气体等因素的影响,引入当量距离概念,在此基础上建立疏散路径选择模型,采用改进的A*算法快速求取最优疏散路径。选取郑州某大厦进行仿真实验,结果表明,实际距离最短的路径并不是最优疏散路径,同时,最优疏散路径随着有毒气体浓度的变化而相应的变化,这样有利于人员的安全疏散。To get the optimal evacuation path that can help people evacuate fast and safely when a fire occurs in a building, this paper sets up the evacuation route choice model based on the equivalent length according to the factors of the fire risk in the building and different development stage of the fire. It gets the optimal evacuation path fast with the improved A ＊ algorithm. After the simulation experiments on a building of Zhengzhou, the results show that the actual distance of the shortest path is not the most optimal evacuation route, and according to the change of the development stage of the fire, the optimal path also makes corresponding changes which are beneficial to evacuate safely.
