中庭式地铁车站公共区防排烟系统优化设计探讨

Discussion on Smoke Control System Optimization Design of Public Area at Atrium-style Metro Station

针对中庭式地铁车站的特殊空间形式及火灾特点,在满足该类型车站公共区防排烟系统功能需求的前提下,为了使该系统配置模式更为紧凑,功能区域划分更为合理,通过对目前国内典型中庭式地铁车站公共区防排烟系统设计方案的综合分析与对比,提出在防烟分区划分、防排烟系统的配置和防排烟系统控制方式等方面的优化解决方案。

In view of special space form and fire characteristics in the atrium-style metro station, the purpose of this research is to make the smock control system configuration mode more compact and the function zoning more reasonable, on the premise of meeting the functional requirements of smoke control system. Through comprehensive analysis and comparison on the design schemes of typical domestic atrium-style metro stations at present, the paper puts forward the optimal solution scheme in light of several subjects, such as smock control zoning, configuration and control mode of smock control system and so on.
