| Abstract: | The construction, the bearing replacement and the girder adjusting are carried out for the prestressed concrete bridge, Suyang Bridge. The displacement and the strain of the girder are measured timely. According to measurement result, the safety of the construction for the bearing replacement and the girder adjusting is guaranteed. The construction of the project is finished without traffic interruption. Finally, according to the figure measurement of the bridge after the construction, the desired result of the construction is testified. |
