| Abstract: | For a prestressed concrete curved box girder bridge, the interior bracket transition at the inner side of pier circular curve has 2cm dislocation; the middle consolidated concrete filled steel tube pier has 6.4cm offset to the outer side of circular curve. The demand on safety and service performance of bridge are met by reinforcement. Analyzing the causes of problems and putting forward practicable reinforcement projects can provide reference to the disposal of bridges with similar troubles. |
