摘　　要：由于地形和结构的特殊性,下穿铁路立交桥的排水系统较为复杂。论文以合肥市肥西县某城市主干道下穿铁路立交工程为例,通过分析下穿铁路立交工程特点和道路周边地形地势,阐述了下穿铁路立交桥雨水排水系统的设计要点和相关参数,解析了下立交区雨水汇水面积选取、外水截流方式方法、泵站工艺设计中存在的重难点。Due to the particularity of terrain and structure,the drainage system of underpass railway overpass is more complicated.This paper takes the railway interchange project under an urban main road in Feixi County of Hefei City as an example,by analyzing the characteristics of the underpass railway interchange project and the terrain around the road,this paper expounds the design key points and relevant parameters of the rainwater drainage system of the underpass railway interchange,and analyzes the important and difficult points in the selection of rainwater catchment area in the underpass area,the ways and methods of intercepting the external water,and the process design of the pumping station.
