摘要
对地铁车站而言,不同的站内布置方案其疏散能力也不同,如何在疏散设施相同的情况下,进一步提高地铁车站的疏散效率尤为重要。以上海某地铁车站为例,在不改变有效疏散设施数量和有效宽度的情况下,将车站内的疏散设施重新组合以增加乘客有效进站点的数量,以此对车站的布置进行优化,并采用BIM软件建立车站模型,利用Pathfinder软件对车站原布置方案和优化后方案的人员疏散进行仿真,对人员疏散路径、疏散时间、楼扶梯使用情况和闸机使用效率等进行分析,结果表明:增加地铁车站有效进站点后,车站内两侧扶梯的累计使用人数减少,中部楼梯的累计使用人数增加,有效改善了乘客疏散过程中在楼梯上产生的拥堵,可以有效减少站内人员的疏散时间,相比原方案疏散时间减少了15.9%,优化后的方案提高了楼扶梯的服务效率,更有利于地铁车站内乘客的疏散。
For metro stations,different station layout schemes have different evacuation capacities.How to further improve the evacuation efficiency of metro stations under the same evacuation facilities is particularly important.This paper takes a metro station in Shanghai as an example.Without changing the number and width of effective evacuation facilities,the evacuation facilities in the station are recombined to increase the number of passengers entering the station effectively,so as to optimize the layout of the station.The station model is established by BIM software,and the Pathfinder is used to simulate and analyze the personnel evacuation,and the personnel evacuation path,evacuation time,use of building escalators and the use efficiency of gate are analyzed.The results show that after increasing the effective entry of the metro station,the cumulative number of escalators on both sides of the station decreases,and the cumulative number of stairs in the middle increases,which effectively improves the congestion generated in the stairs in the process of passenger evacuation,and can effectively reduce the evacuation time in the station.Compared with the original scheme,the evacuation time is reduced by 15.9%.The optimized scheme improves the service efficiency of the stairs,and is more conducive to the evacuation of passengers in the metro station.
