摘　　要：重点研究双薄壁桥墩T形刚构桥的设计要点。依托黄韩侯铁路2×64 m T形刚构桥,采用有限元分析方法,建立全桥模型进行计算,研究桥墩横撑内力特性,采用圆弧形预应力横撑能较好地解决双薄壁桥墩横撑配筋设计。This paper studies the design main points of T shaped rigid frame bridge with double thin-wall pier. Relying on the design of 2×64m T shaped rigid frame bridge on the Huangling-Hancheng-Houma Railway, using finite element analysis, this paper introduces the characteristics of internal forces of the cross-brace. The study shows that arc shaped pre-stressed cross-brace can a better solution for the design of the cross-brace reinforcement for double thin wall piers.
