摘要
高校教学楼作为人员密集的公共场所,在突发事件下人员安全疏散至关重要.由于密集场所中常常存在基于社会关系维系的小团队现象,提出了一种改进的社会力模型,并引入群体效应概念,将每个小团队视作1个行人整体,考虑其亲密度,分析社会力模型中行人间的3种作用力,重点研究小团队行为特征对疏散过程的影响.结合社会力模型对小团队行为特征进行分析,讨论1~5人的5种小团队组合.使用Python语言建模,对行人趋向于以小团队形式疏散的现象进行仿真模拟.结果表明,在密集人群疏散中,适当的团队配置可以显著提高疏散效率,而过多的单人或大型团队则可能导致效率下降.同时仿真显示,以团队形式疏散时,合理的团队人数和比例有助于提高疏散过程的整体效率和安全性.
College academic buildings,as densely populated public places,play significant roles when it comes to safe evacuations during emergencies.Recognizing that social relationships often lead to the formation of small groups in these environments,this study introduces an improved social force model that incorporates group dynamics.Each small group is treated as a cohesive unit,with a focus on their closeness,and the model analyzes three types of forces influencing pedestrian movement.The study explores the role of small group behavior in evacuation scenarios,examining configurations ranging from single individuals to groups of up to five members.By employing Python-based simulations,simulations are conducted under the situation that pedestrians tend to be evacuated in small groups.The findings reveal that strategically sized groups can enhance evacuation efficiency in crowded situations,and that either too many individuals are evacuated alone or overly large groups are evacuated can hinder efficiency.These simulations indicate that well-organized,appropriately sized groups can contribute to safer and more efficient evacuations in academic buildings.
