(School of Civil Engineering, Xi'an University of Architucture and Technology, Xi'an 710055, China)Abstract: Many hyperbolic arch bridges which were built during the early period of China were designed with low load levels and narrow bridge. As traffic and heavy vehicles increased,as well as poor overall performance of the hyperbolic arch bridge itself, there are serious structural defects, which affect traffic operations. This paper mainly combines with a detection of hyperbolic arch bridge in China, and introduces a method of evaluating the carrying capacity of a bridge though the static loading test in detail and gives some reinforcement advices.
Keywords: hyperbolic arch bridge; structural defects; detection; static load test; reinforcement
