摘　　要：以某省会轨道交通预应力简支箱梁为研究对象,通过ANSYS有限元软件对梁体在静荷载和动荷载两种荷载作用下进行模拟分析,重点对动荷载作用下梁体的动态响应进行分析,通过对设计规范要求、现场实测数据与计算结果进行对比分析,达到对箱梁结构合理性进行评定的目的,同时也为预应力箱梁现场施工提供参考。In this paper, a prestressed simple box girder rail traffic of a provincial capital is the research subjects. Simulation analysis has been conductted by ANSYS finite dement software of the beam in the static load and dynamic load, the next focus on the dynamic loads of the dynamic response of the beam is analyzed through the design specifications, field data and calculation results coMParative anal- ysis, and achieves the box girder structure rationality assessment purposes, but also for prestressed box girder construction site for reference.
