摘要: 地下城市通廊具有形态复杂、周围衔接的空间多、内部功能和人员组成多样的特点,在现行的规范中没有直接的解决方案。对城市通廊的形态和特点进行了论述,对一种跨越多层、与地铁融合的多层城市通廊的形式提出了防火分隔和人员疏散的解决方案,并与常规设计进行分析对比。分析表明,城市通廊虽然放弃了传统的防火分区的概念,但是围绕商业进行防火分隔的方案不仅可以满足平面布局的要求,还可以更好地控制火灾蔓延的风险。人员疏散系统的设计要求很好地对现有不同规范之间进行了衔接,既保持了消防安全水平,也兼顾了项目的经济效益。

Abstract: Pedestrian corridor is generally featured by complicated space, multiple interfaces, variable functions and occupants and its fire safety design is beyond the scope of current codes or standards. The concept of underground pedestrian corridor was explored with comparison against underground commercial street. Using a two-story pedestrian corridor in a super underground transportation hub that connects one train station and two subway stations as well as retail facilities as an example, this paper proposed the fire safety design principles and solutions regarding fire separation and prevention of fire spread and the provision of means of egress, based on fire risk analysis to the unique space feature and function. The proposed solution maintained the fire safety standard, with full consideration to the economical balance for operation.
