摘　　要：为研究体育馆人员常态下的疏散特征,采用疏散实验观测和计算机模拟的方法,分别研究常态下人员的疏散行为。研究结果表明,常态下实验测得的疏散时间是182 s,计算机模拟火灾时疏散时间为147s。通过疏散实验和计算机模拟对比得出,常态条件下,整个疏散过程流量系数基本保持恒定,疏散实验流量系数小于软件模拟时流量系数;火灾时数值模拟疏散时间小于常态下观测实验的疏散时间。In order to study evacuation behavior of gymnasium building, this paper adopts methods of evacuation experimen- tal observation and computer software simulation, to respectively research persons behavior in normal conditions. The re- search result shows that under normal condition of experimental evacuation, the need time is 182s, and emergency evacua- tion of simulation need time is 147s. The comparison between the evacuation experimental observation and computer software simulation shows as follows： in normal conditions, the flow coefficient is nearly constant during the whole evacuation time and the flow coefficient of evacuation experimental is less than that in software simulation; evacuation time needed in emer- gency situation is less than that in evacuation experimental.
