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2×64m 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 2í64m 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.
