对隧道排水设计中关键性问题的探讨

城市下穿隧道是城市立体交通的重要组成部分，但隧道排水目前尚未形成专门的适用性设计规范。以桐乡市乌镇大道隧道的排水设计为例，通过研究隧道排水工程与隧道、道路、电气等相关专业的横向关联，对排水设计中防淹涝措施、泵站收水系统、泵站设计等几个关键性问题进行总结，从而进一步保障日后隧道的使用安全。

Discussion on Key Problems in Tunnel Drainage Design

Urban under-cross tunnel is an important part of urban three-dimensional traffic, but there is no specific applicable design specification for tunnel drainage at present. Taking the drainage design of Wuzhen Avenue Tunnel in Tuxiang as an example, the horizontal relationship between tunnel drainage engineering and tunnel, road, electrical and other related majors is studied, and several key problems in the drainage design of anti-waterlogging measures, water collection system of pumping station and design of pumping station are summarized in order to further ensure the using safety of tunnel in the future.
