Discussion on the Smoke Control Scheme in Public Area of the Subway Station

随着地铁的不断建设,地铁车站形式越来越复杂,车站公共区的防排烟方案也越来越多样。同一地区不同车站形式,同一车站形式不同地区的防排烟方案不尽相同。面对不同的车站形式,在满足规范的前提下采用何种排烟方案是防排烟设计首要考虑的问题。文章根据国家现行规范要求,对目前已开通或即将开通的地铁车站公共区常用的排烟方案进行了分析,为防排烟设计工作提供参考。

With the continuous construction of the subways,the form of the subway station is becoming more and more complex,and the smoke control schemes in the public area of the station are becoming more and more diverse.Different station forms in the same area and different areas in the same station form have different smoke control schemes.In the face of different station forms,what kind of smoke exhaust scheme is adopted under the premise of meeting the specifications is the primary consideration of smoke control design.According to the current national specifications,this paper analyzes the commonly used smoke exhaust schemes in the public areas of subway stations that have been opened or are about to be opened,in order to provide reference for the smoke control design work.
