| Abstract: | Reinforced concrete confining method based on dead load adjusting of spandrel structure is expatiated in the paper; besides the engineering measures of dead load adjusting are stated. Through the comparision of the survey of the arch curve variety, the strengthening practice achieves tangible results. The effectiveness shows that the strengthening method is applicable and reliable and it could be a successful practice for repairing and strengthening the similar bridges. |
