| Abstract: | The original rib arch is changed to a slab rib arch in the typical drawing for lightweight rigid-framed arch bridges, and reinforcements are properly added. That the structure strength is increased and structure rigid increased too in the same time. On the basis of rebuilding engineering of Longcuan Bridge over Dongjiang River, a improved design and construction key points of rigid-framed arch bridges are introduced in this paper. |
