摘要： 以郑州市紫荆山地铁站的站台二号线列车火灾和站厅公共区火灾为例，结合GB/T 33668-2017《地铁安全疏散规范》以及NFPA 130- 2017，Standard for Fixed GuidewayTransit and Passenger Rail Systems 中人员安全疏散的相关规定，分别计算疏散时间并对其进行安全评估。计算结果表明：根据GB/T 33668-2017 计算，站台二号线列车火灾时，疏散时间为345.64 s，站厅公共区火灾时疏散时间为339.18 s，均符合6 min的安全疏散要求。而根据NFPA 130-2017 计算，站台二号线列车火灾时疏散时间为557.78 s，站厅公共区火灾时疏散时间为400.46 s，均不符合6 min 的安全疏散要求。最后，针对以上疏散时间计算结果的不同，从疏散过程安全区的选择、疏散路径的选择、疏散设施的疏散能力、人员疏散速度4 方面进行差异分析，为地铁应急疏散相关法规的制订修订和应急管理提供参考。

Abstract:  Taking the fire accidents in the train of Line 2 and on the public zone in the concourse level of Zijing Mountain subway station in Zhengzhou Metro as an example, according to the relevant provisions on occupants' safety evacuation in Code for safety evacuation of Metro (GB/T 33668- 2017) and Standard for Fixed Guideway Transit and Passenger Rail Systems (NFPA 130- 2017), evacuation time were calculated respectively, and also the safety assessment were carried out. The calculation results showed that according to the GB/T 33668-2017, the evacuation time in case of fire in the train of Line 2 is 345.64 s, and 339.18 s in case of fire on the public zone in the concourse level, both of them meet the 6 min safety evacuation requirements. According to the NFPA 130-2017, the evacuation time in case of fire in the train of Line 2 is 557.78 s, and 400.46 s in case of fire on the public zone in the concourse level, both of them do not meet the 6 min safety evacuation requirements. Finally, according to the difference in the calculation results of the evacuation time, the differences from four aspects: occupants' selection of safety zone, occupants' choice of evacuation path, the evacuation capacity of evacuation facilities, occupants' evacuation speed were analyzed. This will provide references for the revision of relevant codes about subway emergency evacuation and subway emergency management.
