| Abstract: | Taking the strengthening technique design of the Louxia Changzheng Bridge （Double-arched stone Spandrel arch Bridge） by RC composite main arch circle method in Guizhou Province as an example,this paper evaluated the bonded reinforcement bridge loading ability based on the methods of limit state method and allowable stress method. Therefore,the results achieved here were very valuable for small and medium span stone arch bridge repairing prolonging the service life of bridge structure. |
