| Abstract: | Firstly, the necessity of discontinuing traffic in construction of strengthening bridge with boncting adjunction is discussed. Then the paper discussed the merits and demerits of the strength, bearing capacity, rigidity, design, construction technology and construction cost of strengthening bridge with bonding steel plate or FRP by using example calculation. The results show that the strengthening effect of bonding steel plate is better than that of bonding FRP for strengthening bridge, but the latter is more economic and easy to construct. |
