Rectification of a Slanted Box-Girder Bridge Caused by Unbalanced Soil Load

Aims: Rectification of a slanted continuous concrete box-girder bridge is presented in this paper. Background: Several piers due to uneven ground settlement, inducing excessive width some expansion joints and oversize sliding displacement bearings. The settlement occured the unbalanced soil load on ground. Methods: In project, reverse loading was first applied produce opposite-direction deformation bending piles, thereby rectifying rigidly connected piles. procedure accelerated by constructing several stress release holes opposite side loading. Results: To stabilize foundation prevent landsides riverbank, combimationn jet grouting piles deep mixed apliied reinforce soil, providing lateral restraint as well. Finally, hydraulic power system used reset piers, girders, joints. A similar additional equipment were replace damaged Conclusion: recommended rectification techniques are suitable for bridges with geotechnical conditions structure types replacing
