| Abstract: | As the construction accident of a ramp bridge beam for the engineering background,the article focuses analysis on the cause of beam cracking.The building and construction units decidedly use the re-cable tensioned prestressing scheme in time according to the primary inspecting test result and construction status.The inspecting test result shows that it is reasonable to use the treatment scheme for this accident.The effect is obvious.The relative experience can be referred for the similar projects. |
