京沪高速铁路跨104特大桥现浇箱梁D段施工设计

The construction design of cast-in-place box girder D of across 104 super bridge of Beijing-Shanghai high-speed railway

以京沪高速铁路跨104特大桥现浇箱梁D段施工为例,着重计算了箱梁的应力及变形等,并总结了现浇箱梁设计过程的经验,同时对贝雷梁、支架钢筋进行了检算,为今后类似跨路现浇桥梁的施工提供了参考。

Taking the cast-in-place box girder D of across 104 super bridge of Beijing-Shanghai high-speed railway as an example, emphatically calculated the stress and deformation of box girder, and summarized the experience in cast-in-place box beam design process, at the same time calculated the Bailey beam, bracket steel pipe, provided reference for future similar across road cast-in-situ bridge construction.
