根据地铁车站的实际情况,结合设计中遇到的实际问题对地铁车站的防排烟系统设计进行了探讨,认为在地铁车站设计中应尽量简化防排烟系统,车站公共区可以划分为站厅、站台两个防烟分区,设备及管理用房采用以密闭防烟为主、走道排烟为辅的方式可以节省空间,降低地铁造价,提高系统的可靠性。 According to the actual situation of the subway station, with the practical problems encountered in the design of the subway station smoke exhaust system design is discussed, that in the metro station design should try to simplify the smoke control system, station public area can be divided into station hall Two anti-smoking stations on the site, equipment and management of the main use of confined smoke-based, aisle walkway smoke supplement can save space, reduce the cost of the subway and improve system reliability.
