地铁隧道通风系统活塞风井布置探讨

摘要

介绍了地铁隧道通风系统中单、双活塞两种系统的工作原理,从工程造价、运行能耗等方面对单、双活塞两种隧道通风的系统形式进行比较和分析,结论认为单、双活塞系统各有优缺点和使用范围,给出了单、双活塞系统各自适用区域的应用建议:地铁在车站周边环境条件允许的情况下,尽量采用双活塞系统；但在站间距较小,且风亭设置用地较困难的情况下,车站可设置单活塞系统.%The working principle of single and double piston air shafts in subway is introduce, their engineering cost and operating energy consumption are compared, the appropriate system in appropriate metro station construction is proposed.
