地铁车站段隧道（半）横向通风系统方案溯源及适用性研究
Origin and applicability of tunnel (semi) transverse ventilation system of underground railway station
摘要：
早期建设的欧洲城市轨道交通线路中，未对地下站车站段隧道设置横向或半横向通风系统。基于1975年多伦多实验，美国《地铁环境控制手册》最早提出在车站段隧道设置（半）横向通风系统。国内自上海地铁1号线以后的多数地铁线路均采用此种设计方案，即在车站段隧道设置轨顶及站台下排热风道。结合非屏蔽门制式和屏蔽门制式特点，对车站段隧道采用（半）横向通风方案和空调方案进行权衡判断，提出了（半）横向通风经济性的判定式。
Abstract：
No trackway exhaust system has been built in earlier European and American underground railway projects until 1970s, when Subway environmental design handbook recommended overtrack and underplatform exhaust ducts adopted in station configuration, based on Toronto field test in 1975. Since Shanghai underground railway line 1, most of the underground railway lines in China adopt the semitransverse ventilation design scheme. Based on the characteristics of nonscreen door system and screen door system, presents the tradeoff method on the (semi) transverse ventilation scheme versus air conditioning scheme, and deduces the decision formula of economic performance of (semi) transverse ventilation scheme.
