摘　　要：近年来发生的火灾多在人员密集场所,当突发事件发生时,人员疏散往往特别困难,因此,规划行人在大型公众聚集建筑物中的疏散路径非常重要。基于能见度图建构的元胞疏散最短路径模型可直接用于实际的紧急疏散指示路径的规划,避免设置大量逃生指示装置致使工程成本过高及视觉不美观,并且也解决了有限制逃生指示装置数量当作限制条件的最大涵盖面积的求解复杂、空间大的问题。During recent years, the fire disasters often happen in crowed places. Human evacuation is usually very difficult, in case of emergencies. Therefore, it is very important to standardize the evacuation of pedestrian in public gathering constructions. The shortest- path model of cellular evacuation constructed based on visibility chart can directly be applied in the plan of indicating path of actual emergency evacuation, which not only avoids high cost and unaesthetic visual caused by large quantity of escape indicating devices, and solve the large space and complex problem of largest covering size when regarding restricted quantities of escape indicating devices as restricted condition.
