| 摘 要： | 为分析大型地铁枢纽车站人员疏散通过能力、疏散瓶颈位置和车站疏散策略优化方案，利用数值模拟研究某大型整体式站厅枢纽换乘车站人员疏散过程。研究结果表明:楼扶梯和出入口是车站疏散过程中的关键瓶颈，当疏散通过能力较大的出入口E或楼扶梯组8停止使用时，导致站厅疏散时长和站台疏散时长大幅增加；采用引导乘客均匀使用各楼扶梯疏散以及站厅增加应急出口等优化措施，可显著提高车站疏散效率。

| Abstract: | To analyze the evacuation passing capacity,evacuation bottlenecks location and optimization scheme of evacuation strategy in large metro hub stations,the personnel evacuation process of a large metro interchange hub station with integral station hall was studied by numerical simulation.The results showed that the key bottlenecks in the evacuation process were the stairs,escalators,entrances and exits.When the facilities with large evacuation passing capacity such as entrance and exit E or stair and escalator group 8 stopped working,the evacuation time of station hall and platform would increase greatly.After guiding passengers to evenly use the escalators and stairs and adding the emergency exits in station hall,the evacuation efficiency was significantly improved. |
