摘　　要：以德大铁路32 m铁路槽型梁为工程背景,对其设计标准、主梁构造及计算分析进行介绍。该结构具有设计时速高、截面形式新颖的特点,采用有限元分析软件对结构进行整体计算,并对车桥耦合振动问题进行动力仿真分析。Taking the 32 m-span U-shaped beam of Dezhou-Dajiawa Railway as an engineering background,this paper introduces its design standards,main beam structure and calculation analysis. This structure has the characteristics of high design speed and novel cross-section form. The finite element analysis software is used to calculate the overall structure, and the dynamic simulation analysis of the vehicle-bridge coupled vibration problem is performed.
