| 摘 要： | 连续箱梁是城市轨道交通高架区间的一种常用结构形式，它具有投资节约、建设周期短、结构刚度大等优点。结合深圳轨道交通5号线高架区间的设计，对三跨等高度连续箱梁的配束方式及腹板束在梁端的张拉措施进行了比较和分析，可为轨道交通高架区间上部结构设计提供参考。

| Abstract: | Continuous box girder,as a common structure in urban rail transit elevated section,has the advantages of low investment,short construction period,and high rigidity.Taken elevated interval design of Shenzhen Rail Transit Line 5 as example,prestressed tendon arrangement and detailing measures of web tendon tensioning on beam-end is comparatively analyzed for three-span continuous box girder with same height,which will be referred for the design of upper structure of rail transit elevated interval. |
