摘　　要：地铁车站具有客流密集、空间狭长的特点,若发生火灾,可能造成严重的人员伤亡及财产损失。系统的消防设计是保证乘客安全、维护经济利益的重要环节。常规设计中,站台层设备区临轨行区走廊与公共区之间未进行防火分隔,存在安全隐患。文章基于现行规范及工程经验提出的两个解决方案,都可以从规范符合性上解决站台层设备区走道的消防疏散问题,保证其安全性和可靠性。虽然方案可能扩大车站规模,但相对消防安全而言是值得的。The subway station has the characteristics of dense passenger flow and narrow space.If a fire occurs,it may cause serious casualties and property losses.The systematic fire protection design is an important link to ensure passenger safety and safeguard economic interests.In the conventional design,there is no fire separation between the corridor and the public area in the equipment area of the platform floor,which poses a potential safety hazard.Based on the current specifications and engineering experience,two solutions proposed in this paper can solve the fire evacuation problem of the corridor in the equipment area of the platform floor from the perspective of compliance with the specifications,and ensure its safety and reliability.Although the scheme may expand the scale of the station,it is worthy from the perspective of fire safety.
