摘　　要：大量人群的紧急疏散问题是城市管理和基础设施建设中的重要课题。同时,对大量人群的集体运动进行建模、仿真和理论研究也是国内外学者关注的问题。基于最近发展的改进的社会力模型,对普通房间中的人群疏散过程进行一系列系统的模拟研究。该改进的社会力模型额外引入行人运动随机性对人群集体运动行为的影响。因此,它可以更真实地研究各种人群疏散行为。系统地研究出口宽度、人群密度等因素对疏散过程特别是人群阻塞行为的影响。The problem of emergent evacuation is of obvious importance in the city management and the infrastructure construction.At the meantime,study on pedestrian behavior is also very crucial and has attracted lots of research attention.Systematically study the crowd evacuation in a common room,based on a recently developed modified social force model.This model includes the important impact of randomness on the pedestrian behavior,and can simulate the collective movement of pedestrians more accurately.The influences of various factors,such as the exit width,the crowd density,etc.,on the evacuation behavior were carefully investigated,especially concerning the grouping and clogging behavior.
