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 comparislon of the survey of the arch eLLrve variety,the strengthening practice achieves tangible results.The effectiveness shows that the strengthening method is applieable and reliable and it could be a successful practice for repairing and strengthening the similar bridges.

Key words: stone arch bridge, strengthening, reduction of load, high pressure grouting , reinforced concrete confining
