介绍人流恐慌行为模拟模型社会力模型,分别分析人员恐慌行为对闸机疏散效率和自动扶梯疏散效率的影响,认为期望速度为约1.5m/s时,闸机疏散时间最短,随着期望速度的增大,疏散时间增加,闸机通行能力降低,若人员表现出恐慌行为,闸机和自动扶梯口的疏散效率分别为有序疏散的50%和70%。该结果对地铁设计规范的制定及地铁站设计具有指导意义。
This paper introduces the social force model of panic behavior simulation model and analyzes the influence of staff panic behavior on evacuation efficiency and evacuation efficiency of escalator respectively. When the expected speed is about 1.5m / s, the evacuation time is the shortest. With the expected speed Increase, evacuation time increases, gate capacity decreased, if the staff showed panic behavior, gates and escalators mouth evacuation efficiency were 50% and 70% of the orderly evacuation. The result is of guiding significance for the design of subway design and subway station design.
