高速铁路越江隧道排水泵房设计探讨

Discussion on design of drainage pump station for the crossing-river tunnel of high-speed railway

针对国内目前无相关规范指导越江隧道排水泵房设计的现状,根据国内已建高速铁路越江隧道的特点,对其排水泵房集水池调节容积、水泵配置、降雨历时和设计重现期等主要设计参数进行了探讨,可为我国今后高速铁路越江隧道排水泵房设计提供参考。

Based on the current situation that there is no related standards for the design of drainage pumping station in China and the characteristics of high-speed railway crossing-river tun- nel, the main design parameters of drainage pump station, which included regulating volume of wa-ter collection tank, pump configuration, duration of rainfall and design recurrence interval were discussed. This paper could provide a reference for design of drainase pump station for the high- speed railway crossing-river tunnel in future.
