| 摘 要： | 地铁换乘枢纽车站结构复杂、客流密度高，火灾情况下的应急疏散难度大，为研究地铁大型换乘枢纽火灾事故时的客流疏散模式，以四线换乘枢纽CGM站为例，使用building EXODUS软件，分别研究楼梯组、电梯、出入口和闸机组这4类设施无法使用时对乘客疏散时间的影响，以及各场景下乘客的疏散策略。考虑仅站厅乘客参与疏散、1辆列车上的乘客参与疏散、2辆不同线路列车上的乘客参与疏散这3种情况，共设置155个工况。研究结果表明:出入口对于疏散时间的影响较大；楼梯组次之；电梯和闸机组的影响明显小于前2者；同类设施中，由于设施位置及几何特征存在差异，各设施对于疏散时间的影响不同；随着疏散人数的增加，同一设施对于疏散时间的影响随之增加；所有出入口可以使用时，各线路独立疏散时效率较高；发生出入口火灾时，打开线路间换乘通道的防火卷帘门可降低所需疏散时间。

| Abstract: | The metro transfer hub station has the characteristics of complex structure and large passenger flow density,so the emergency evacuation in case of fire is difficult.In order to study the passenger flow evacuation mode in the fire accident of the large transfer hub of metro,taking the four line transfer hub CGM station as an example,the building EXODUS software was used to study the influence of unusable stairs group,elevators,exits and gate group on the evacuation time of passengers respectively,as well as the evacuation strategy of passengers in each scene.155 conditions were set with considering three types of situation that only the passengers in the station hall participated in the evacuation,the passengers on 1 train participated in the evacuation,and the passengers on 2 trains in different lines participated in the evacuation.The results showed that the exits had greater influence on the evacuation time,followed by the stairs group,while the influence of elevators and gate group were obviously less that the former two.Among the similar facilities,different facilities have different influences on evacuation time due to the different location and geometric characteristics.As the number of evacuees increases, the influence of the same facility on evacuation time increases.When all the exits were usable,the efficiency of independent evacuation of each line was higher.In case of the passageway fire,opening the fire shutter door of the transfer channel between lines could reduce the evacuation time. |
