| 摘 要： | 针对地铁车站中的人员疏散问题,设置5种疏散场景,运用FDS+Evac进行数值模拟,得出各场景下自动扶梯与人行楼梯平均疏散能力和疏散时间,并与《地铁设计规范》中人员疏散时间计算公式得出的结果进行对比分析。研究结果表明:我国现行《地铁设计规范》中自动扶梯和人行楼梯通行能力折减系数取值偏大,宜从0.9调整为0.772。

| Abstract: | In order to discuss the safety evacuation for occupants in metro station,five evacuation scenarios were presented,and then simulated by FDS+Evac.The simulation results were compared with the calculation results according to the formula 8.3.10 in national Code for Metro Design.The analytical results show that traffic capacity reduction factor of escalators and stairs pedestrian in the national Code for Metro Design is too large,and should be reduced to 0.772 from 0.9. |
