基于改进社会力模型的地铁大客流疏散能力研究*

为有效应对大客流情景下人群拥挤对地铁站正常运行带来的影响，采用社会力模型和Anylogic仿真软件,对地铁站大客流疏散能力进行建模和分析,从客观、主观、管理视角分析影响客流疏散能力的因素，基于改进社会力模型刻画行人行为，分析影响地铁车站疏散能力的3个关键因素，并以南宁地铁1号线朝阳广场站为背景进行研究。研究结果表明:行人密度是影响地铁站疏散能力的关键因素，出入口选择策略和行人亲属关系比例对疏散能力影响显著，研究结果可为地铁客流疏散提出针对性建议。

Research on evacuation capacity of large passenger flow in subway based on improved social force model

In order to effectively deal with the influence of crowd congestion on the normal operation of subway station in the case of large passenger flow,the social force model and Anylogic simulation software were used to model and analyze the evacuation capacity of large passenger flow in subway station.The factors affecting the evacuation capacity of passenger flow were analyzed from the objective,subjective and management perspectives,and the pedestrian behavior was described based on the improved social force model.Three key factors affecting the evacuation capacity of subway station were analyzed,and the research was conducted on the background of Chaoyang Square Station of Nanning Metro Line 1.The results showed that the pedestrian density was the key factor affecting the evacuation capacity of subway station,and the selection strategy of entrance and exit and the proportion of kinship among pedestrians had significant impact on the evacuation capacity,which can provide targeted suggestions for the passenger flow evacuation of subway.
