| Abstract: | The construction scheme of segment precasting and full span girder erection by 3 200-t overhead launching gantry was adopted for the 64-m span simply-supported concrete box girders of Baima River Bridge on Wenzhou-Fuzhou Railway. This paper presents the successful experiences in aspect of precasting, storage and transportation of the segments of the concrete box girders, application of the large capacity overhead launching gantry, erection of the girders by the gantry, hauling and traveling of the gantry, and consideration and control of influence of action forces from the main truss girder of the gantry on the concrete box girders at the time the prestressing strands were jacked. |
