摘要
重大事故发生时 ,应急疏散行动过程中 ,疏散空间网络的各节点 ,都有可能出现排队等待疏散服务的现象 ,甚至可能会引起人们互相拥挤 ,造成恐慌及群集事故的发生。应急疏散空间的各种不同类型应急疏散排队系统 ,其服务性能主要取决于服务系统的极限容量、疏散服务能力的随机性等。本文首先对应急疏散空间排队疏散服务系统的基本变量进行定义和讨论。进而建立关于人员应急疏散性状的数学模型。并以单元疏散空间为例 ,进行应急疏散空间排队网络分析法的计算机模拟 ,与理想疏散状态下模拟结果进行对比分析 ,分析应急疏散系统的疏散性能和群集滞留现象。
When hazards happens,in the process of emergency evacuation,it's extremely possible for the evacuation crowd to queue a long time and wait for evacuation services at every nodes in the evacuation space, which will result in human's congestion with each other , panic and crowd congestion hazard. Emergency evacuation spaces have various different type of emergency evacuation queuing network, its service performance mainly depends on the extreme volume、evacuation service capacity, etc. Based on the definition of basic stochastic parameters of queuing evacuation system , this paper discusses the establishment of the mathematical model of emergent evacuation queuing network so as to set up the computer simulation on the emergency evacuation queuing network and its application in unit evacuation space, and compare its simulation result with the ideal evacuation status .Finally, it analyses the evacuation performance and crowd congestion phenomenon. The research result will surely do some important help to the city disaster\|defend engineering ,and will make the safety science theory develop further.
