导流栏杆设置对地铁岛式站台人员疏散的影响分析

为研究导流栏杆设置对地铁岛式站台人员疏散效率的影响,选取不同出口分布类型的地铁岛式站台为研究对象,基于BuildingEXODUS软件进行数值模拟,分析导流栏杆设置对不同出口分布类型地铁岛式站台人员疏散的影响.研究结果表明:A型站台在设置导流栏杆后,人员疏散时间均有所增加,导流栏杆设置长度为2,4 m时,人员疏散时间增...

Analysis on influence of diversion railing setting on personnel evacuation of subway island platform

In order to study the influence of the setting of diversion railing on the personnel evacuation efficiency of subway island platform,the subway island platforms with different types of exits distribution were selected as the research objects,and the numerical simulation was carried out based on BuildingEXODUS software to analyze the influence of the setting of diversion railing on the personnel evacuation efficiency of subway island platform with different types of exits distribution,so as to provide reference for the subway passenger flow organization and operation safety.The results showed that for the type A platform,the personnel evacuation time increased after the setting of diversion railing,and the increase of personnel evacuation time was smaller when the length of diversion railing was 2 m and 4 m,while when the length of diversion railing was 6 m,8 m and 10 m,the increase of personnel evacuation time was larger.For the type B platform after the setting of diversion railing,the personnel evacuation time decreased first and then increased with the increase of the length of diversion railing under the same number of evacuation personnel,and the personnel evacuation time was the shortest when the diversion railing was set as 4 m.For the type C platform after the setting of diversion railing,there was little change in the personnel evacuation time.Compared with the type C platform,the personnel evacuation efficiencies of type A and type B platforms were more susceptible to the setting of diversion railing.
