为了分析单室中双出口布局和出口宽度对疏散时间的影响,运用Pathfinder软件模拟,探讨双出口在对称与非对称情况下疏散时间的变化情况以及出口宽度的变化对于疏散时间的影响。介绍了模拟场景的设置和各参数的选取。结果表明出口位于墙壁中央时,疏散效率最高,疏散时间不随出口宽度的增加而持续减小。 In order to analyze the influence of double exit layout and exit width on the evacuation time in single room, the paper uses the Pathfinder software simulation to study the evacuation time of double exit under symmetrical and asymmetrical conditions and the influence of exit width on evacuation time. The setting of simulation scene and the selection of each parameter are introduced. The results show that the evacuation efficiency is highest when the exit is located at the center of the wall, and the evacuation time does not decrease continuously with the increase of exit width.
