【 摘 要 】

The separated interchange bridge described in this paper has a large bevel angel and its superstructure is combined steel and concrete girder. The bridge shakes significantly when heavy-loaded vehicles travel on it. Moreover, the box girder has warped upwardly and the bearing has disengaged with the girder body. Therefore, a static load test on the bridge has been performed. By the test, corresponding results have obtained, damage conditions and bearing capacity have been analyzed and evaluated, and measures to prevent bridge defects have been proposed. Finally, a maintenance and reinforcement scheme has been formulated, which has a reference significance for overall inspection and evaluation of the similar old bridge.
