Study On Tied-Arch Bridge Of Reinforced Concrete Detection And Strengthening Technology

China’s rapid economic development, China’s growing demand for roads and bridges,with the development of the logistics.30years of reform and opening up, China has builtmany bridges. But the existing bridge, carrying capacity has declined. For all our existing oldbridge reconstruction, high cost, feasibility is not strong. Test and assess the repair andreinforcement, the old bridge to become a hot issue of academia and business circles.In this study, the authors through case studies, to analyze an example of a reinforcedconcrete tied arch bridge reinforcement overhaul case, the detection and evaluation, as well asfor reinforced concrete tied arch bridge repair and reinforcement technology, carefully studied.This study confirmed that the appropriate method to clear the existing state of the bridge, andon this basis, to take reinforcement technology, the bearing capacity of the old bridge, throughthe reinforcement technology can restore restore access features of the bridge, whicheffectively extend the bridge life limited cost, to achieve better outcomes.Tied Arch Bridge practical,1950s, tied arch bridge is widely used in bridge constructionin China. Especially in the past20years, the number of tied arch bridge construction isgrowing rapidly. Detection and evaluation and repair of reinforced concrete tied arch bridge,with a strong representation, which is tied arch bridge structure contains a beam, arch, boardsystem, with a wide range Tied Arch Bridge detection and evaluation and maintenance of thesignificance Tied Arch Bridge detection and evaluation and maintenance of research results,and can learn from the other bridge reinforcement and repair.In this paper, case studies, study on the detection and evaluation and maintenance ofTied Arch Bridge Tied arch bridge detection and evaluation using semi-breakage detectionevaluation, no damage detection and evaluation, synthesis method, load test method, using thetied arch bridge maintenance replacement boom Act, expand cross-section reinforcement,CFRP reinforced, prestressed law, epoxy crack treatment, anchorage reinforcement method.This study is based practice and research at home and abroad Tied Arch Bridge detection andevaluation and maintenance, according to the practice of some improvement and innovation.This study, assessment and repair of bridge inspection, has a certain practical significance.
