| Arch bridge is a bridge structure in China is relatively unique and beautiful, more carrying many of our poetry literary history and culture, modern arch bridge based on China Design Bridge hyperbolic arch bridge workers, in the classical aesthetics maintain arch bridge and save more materials. But the lack of rigidity of transverse arch bridge’s congenital, as well as the main arch rib stiffness and reinforcement is partial to weak, with the increasing of the service time, many still has great and beautiful significance of double curved arch bridge repair reinforcement, based on the double curved arch bridge of this unique style and practical problems, the double curved arch bridge the repair and strengthening of in-depth study, has very important practical significance.In this paper, through the investigation and related literatures, according to the special structure of the double curved arch bridge, formation and the cause of structure and disease were analyzed the main arch, arch, pier and foundation. Then, the main arch and arch rib section enlargement method, discusses the CFRP method, bonding steel plate, reinforced arch inter costal horizontal contact law and the external pre method. According to the modified arch into beam arch method and modified arch continuous slab arch construction method. The double curved arch bridge pier and foundation of the gravity type pier (Taiwan) reinforcement method, pushing method to adjust the arch foot horizontal displacement method, anchor method in the reinforcement of U type abutment and hyperbolic arch bridge pier, foundation and foundation reinforcement method.Through the reinforcement and repair engineering a hyperbolic arch bridge, the reinforcement scheme and construction technology in the theoretical part of this article as a guide, and in strengthening of bridges are studied respectively before and after the static load test, the full test of the reinforcement effect, strengthening effect is obvious. |
