地铁特殊配线车站的隧道通风系统配置

Configuration of Tunnel Ventilation System at Subway Special Assistant Line Station

对特殊配线车站土建、配线形式进行分析,提出特殊配线车站隧道通风系统四种配置方案。对四种方案进行初投资及功能分析,提出推荐方案:有条件的配线车站可采用隧道通风系统设在配线上的方案二;站后有商业开发的车站,为尽可能减少对商业开发的影响,可考虑采用隧道通风系统设在配线后,并在配线上设置横向排烟风道的方案四。建议结合特殊配线车站的土建形式、外部环境,因地制宜地选取隧道通风系统方案。

Through an analysis of building projects and as- sistant line form at subway station, four configuration plans of tunnel ventilation system are put forward, the initial in- vestment and functions of each plan are analyzed. Accord- ing to technical an economical comparison, each plan is recommended to different conditions, including the station construction, commercial development and the unique ex- ternal environment. It is suggested that the ventlation sys- tem configuration should select suitable project according to the building condition and ambient environment of the sub- way station with special assistant line.
