摘　　要：下穿立交道路由于其纵坡大、位置低,易成为易涝点。结合工程实际案例,从汇水面积划分、雨水量计算、排水收集系统及雨水泵站设计等方面科学阐述下穿立交排水系统的设计参数。此外,论文强调下穿立交排水设计应与道桥设计、排涝除险设计、源头减排统筹考虑,以经济节能的方式达到内涝防治和径流污染控制。The underpass road is easy to become a waterlogging point because of its large longitudinal slope and low location.The design parameters of underpass overpass drainage system are described scientifically from the aspects of catchment area division,stormwater quantity calculation,drainage collection system design and stormwater pumping station design.In addition,the paper emphasizes that the drainage design of underpass overpass should be combined with the design of road and bridge,the design of flood drainage and risk relief,and the source emission reduction,so as to achieve waterlogging prevention and runoff pollution control in an economical and energy-saving way.

关 键 词：下穿立交排水系统 汇水面积 雨水量 雨水泵站
