摘要/Abstract

摘要： 为合理控制人员数量,避免地铁在紧急状态下发生拥挤踩踏事故,根据相关标准对疏散时间的要求,将地铁人群疏散风险等级设定为4级;应用Pathfinder仿真软件建立仿真模型,针对不同地铁乘载率,模拟疏散过程,获取与4个风险等级对应的地铁站台可疏散人员数量及人群密度,并将地铁疏散风险量化分级;结合北京地铁实际情况,分析不同风险等级下地铁承载率与地铁站台人群密度间的函数关系。结果表明:随着站台人群密度及地铁承载率的增加,疏散风险等级提高;在疏散时间一定时,人群密度与地铁承载率有二次多项式关系。

关键词: 人群密度, 地铁承载率, 安全疏散, Pathfinder软件, 风险分级

Abstract: To control reasonably the number of passengers and avoid crowded stamped accidents, evacuation risk was classified into four levels according to evacuation time in the relevant standards. A simulation model was built using Pathfinder simulation software. And according to different subway carrying rates, evacuation process simulations were carried out. The numbers and the densities of evacuated passengers on the subway platform corresponding to the four risk levels were obtained, and the evacuation risk of the subway was quantified and classified. The functional relationships between the subway carrying rate and the crowd density on the subway platform under different risk levels were analyzed according to data on Beijing metro. The results show that there is a positive correlation between the evacuation risk level and both the crowd density on the platform and the carrying rate of the subway, and that when evacuation time is fixed, there is a quadratic polynomial relationships between the subway carrying rate and the crowd density.

Key words: crowd density, subway carrying rate, safe evacuation, Pathfinder, risk classification
