摘要: 城市轨道交通系统中,地下两层岛式站台车站分布广泛。为研究疏散总时间与进站客流量的关系以及作用机理,分析了车站主要疏散设施能力和疏散瓶颈,设计多组别灵敏度仿真分析实验,通过对比同组和组间各仿真模型输出结果,分析仿真疏散过程的差异性。仿真结果表明:随高峰进站人数增加,车站疏散时间会在一定限度内增加,车站疏散总时间与疏散开始时刻站台人数相关。该研究为研究客流与疏散时间的关系提供方法手段,为车站应急疏散组织工作提供参考。

Abstract: Underground two-level island platform stations widely existed in urban rail transit system. In order to analyze the relationship between the evacuation time and the character of passenger flow, the capacity of main evacuation facilities and the evacuation bottleneck of stations are studied, and groups of sensitivity analysis experiment are designed. The variability of the evacuation process is analyzed by comparing the output of each simulation model in a group and between groups. The simulation result shows that the station evacuation time increases within a certain limit at peak hour. And the station evacuation time is mainly affected by the number of pedestrians in the platform at the beginning of evacuation. The methods for studying the relationship between passenger flow character and evacuation time are provided, and which can be a reference for the emergency evacuation organization.

Key words: evacuation, underground two-story island platform station, sensitivity analysis, passenger flow character, equipment passing capacity
