摘　　要：在城市交通和基础设施建设不断发展的今天,U型槽结构越来越地多运用于道路下穿敞开段,而下穿段的强排水泵站常被设计独立于主体结构之外。本文以云南香格里拉市德吉路下穿丽香铁路工程为例,介绍一种内置强排泵站的U型槽设计思路,并对该结构进行有限元计算与分析。As urban traffic and infrastructure develop constantly at present,U-shape groove structure is applied to underpassing open section of road increasingly,and the pumping station for forced drainage at the underpass section is often designed to be independent of the main structure.Herein the project of Deji Road undercrossing Lijiang—Shangri-La Railway in Shangri-La City,Yunnan was taken as an example to introduce a design concept of U-shape groove built in pumping station for forced drainage,and then the finite element calculation and analysis of this structure were carried out.
