Bridge Rectifying and Resetting Control Technique and Its Application
Wang Jingshan;Wang Cuiying;
Under the condition of support construction deviation, the diseases of pier stud tilted, beam longitudinally displaced, expansion joint jammed, and support slipped and removed maybe appear in the first-simple-supported post-continuous-beam bridge in the long-term operation process because of temperature effect and automobile braking force. Taking the above diseases of a bridge in an expressway as an example, the article summarizes its disease causes, and sets forth the technique of using the multi-span synchronous jacking beam and superstructure as the reaction frame for rectifying of bridge pier, which can be referred for rectifying of the similar bridges.
