Proceeded for beam strength and stress; analysis and checking calculations are made of Traverse beam and surface plate.

将所推荐桥梁进行了全面的计算分析，利用横向分布系数确定活载分布，求得上部结构主梁的内力，从而确定主梁配筋，然后进行主梁强度和应力验算，并分析验算了横梁和桥面板。

The arch bending on the top of the original main arch ring corresponds to every arch rib and the bottom beam on its landscape orientation. As a result it becomes a down arc frame similar to slab-and-beam floor system. On the arch bending and bottom beam just established, standing pillar, main beam, horizontal rib beam and bridge front-panel would be built subsequently. Both ends of the main beam would then be put off the new hat beam made of reinforced concrete. Now, it becomes an upper slab-and-beam floor system. Two decks will be joined together on the middle of the bridge, which forms the ability of spanning and loading.

在原主拱圈拱肋相应位置处增设拱伏，横向增设底梁，形成一个下层弧形的类似肋梁楼盖的结构；在已浇筑好的拱伏与底梁上，继续现浇立柱、主梁和横向肋梁、桥面板，主梁的两端搁置在桥台处新增加的钢筋混凝土台帽梁上，形成一个上层肋梁楼盖结构，并且上下两层楼盖在桥梁跨中互为渗透结合成一个牢固的整体，共同完成了跨越和承载的能力。

For partially prestressed concrete I or T girder bridge,there is no sufficient stiffness owing to damage like prestress loss and cracks etc. The experiments of original and reinforced girders have been proved that the effect is remarkable to apply steel and concrete composite reinforcement method.

部分预应力混凝土I型或T型梁桥，由于预应力损失、裂缝损伤等造成主梁正常使用状态下刚度不足，采用钢-混凝土组合加固主梁，通过原梁及加固梁的加载试验，表明加固效果十分显著。

The tower plate utilizes stainless steel double bottom plates welded main beam ,by which welding deformation can be reduced,straight linear degree can be guaranteed, main beam rigidity as well as entire beam stability can be strengthened to resist horizontal orientation live load,and tower height can be lowered as well.
