摘　　要：针对铁路下凹隧道工程设计标准不够详细的现状,根据下凹隧道工程特点,从隧道洞外截排水、洞口接线段雨水排水和洞内废水排水三方面,对排水工程设计参数进行了分析,并探讨了泵房自控仪表及视频监控系统的设置,提出了隧道机械排水系统故障处理遵循不影响行车、天窗点处理的原则以及日常运维管理要求。The current design standards for underpass railway tunnel engineering are not detailed enough.Based on the characteristics of the underpass tunnel,the design parameters of drainage engineering were analyzed from three aspects:external interception and drainage,rainwater drainage of the entrance section,and wastewater drainage inside the tunnel.The installation strategy of automatic control instruments and video monitoring systems in the pump room were discussed.It is proposed to follow the principle of not affecting driving and handling at‘skylight time’in the maintenance of tunnel mechanical drainage systems.The requirements for daily operation and maintenance were also illustrated.
