摘　　要：槽形梁是一种梁、板组合的下承式结构形式,具有建筑高度低、断面空间利用率高、外形美观等特点,特别适用于城市轨道交通跨线、跨河处净空受限制的工程。本文对城市轨道交通35 m双线简支槽型梁的关键设计参数进行了对比分析研究,可为双线简支槽型梁的设计提供参考。U-shaped girder is a through bridge structure,consisting of girder and plate.It is featured by low building height,high utilization of section space and beautiful appearance.As for the urban rail transit,the u-shaped girder is especially suitable for the areas with limited height clearance.The paper makes a comparative analysis of the key design parameters of 35m simply supported u-shaped girder for double track,providing a reference for the similar design.
