| Abstract: | According to different parts and different types of cracks,some strengthening methods for the prestressed concrete continuous box-girder bridges and their corresponding technical requirements are proposed.Several methods have been applied to a bridge strengthening practice.The reasonability and effectiveness of the strengthening method has been proved by the static,dynamic tests,and the two-year operation. |
