摘　　要：[目的]地铁车站站台的楼扶梯宽度、垂直高度、运行速度等因素对行人疏散时间有重要影响,因此需研究地铁车站站台楼扶梯设置参数对行人疏散时间的影响。[方法]基于DICE人群聚集风险模型,通过AnyLogic软件分别仿真分析了楼梯、自动扶梯和楼扶梯组的客流疏散时间。对所提出的模型进行了实例验证。[结果及结论]自动扶梯运行速度对疏散时间影响程度高于自动扶梯宽度和高度对疏散时间的影响;楼扶梯宽度对疏散时间影响程度比楼扶梯高度的大;自动扶梯饱和状态与半走半立状态下的疏散时间存在一定比例关系,该比例与扶梯上选择行走的行人比例有关。实例验证表明,所提出的模型有效可行。[Objective]Factors such as width,vertical height,and operational speed of staircases and escalators on metro station platform impact passenger evacuation time significantly,therefore it is necessary to study the impact of the platform staircase and escalator setting parameters on passenger evacuation time.[Method]Based on DICE(data integration collection environment)passenger gathering risk model,the passenger evacuation time by staircases,escalators and the combination is simulated and analyzed by AnyLogic software.The proposed model is empirically verified.[Result&Conclusion]The impact of escalator operational speed on evacuation time is greater than that of the escalator width and height.The impact of escalator and staircase width is greater than the height.There is a proportional relationship between the evacuation time under escalator saturation state and passengers half-passing half-standing state on escalator,which is related to the proportion of passengers choosing to walk on the escalator.The empirical verification shows that the proposed model is effective and feasible.
