摘　　要：介绍广州地铁4号线的隧道通风系统方案——采用隧道风机变频兼作车站隧道排风机,只在出站端设置活塞风道。与传统的系统方案相比,该系统方案可以大量节省初投资,并可以避免因风机全压选择偏大所带来的运行费用的增加。分析该系统方案的设计原则、设备选型原则等,可供方案推广应用所借鉴。The paper introduces the ventilation system of Guangzhou subway line 4. Variable frequency converse fans were adopted for the running tunnels and for the air exhaust of the station, with only one piston vent shaft set at the station end. Compared with the traditional tunnel ventilation system, this system can greatly save investment and avoid the increase of running expenses arising from the greater wind pressures for ventilation fans. The design principles of the system and the principles of selecting the types of equipment can be served as guidance to the application of the system.
