摘　　要：为研究客流空间分布对地铁车站人员疏散的影响,以某地铁车站为研究对象,采用Building Exodus仿真模拟软件对40种疏散工况的地铁车站人员疏散进行数值模拟研究。结果表明:客流均衡分布时,不同客流量下疏散时间随客流量增加而增加;客流不均衡分布时,相同客流量下客流均衡分布时疏散时间最短,疏散时间随着客流不均衡度的增加而增加,且客流量与疏散时间符合线性函数关系。In order to study the effect of spatial distribution of passenger flow on the evacuation of subway station,Building Exodus simulation software was used to simulate the evacuation of 40 evacuation conditions in a subway station.The results show that the evacuation time increases with the passenger flow under different passenger flow conditions when the passenger flow is balanced.When the passenger flow is unbalanced,the evacuation time is the shortest when the passenger flow is balanced,and the evacuation time increases with the increase of the passenger flow unbalance degree,and the relationship between the passenger flow and the evacuation time is linear.

关 键 词：地铁火灾 空间分布 人员疏散 疏散时间
