| Abstract: | Taking the extra-long bridge on Bao-Xi Railway across the Yellow River as an example, the 48m girder pre-easting technology, including reinforcement processing, formwork fixing, and concrete casting and curing, is introduced. This technology is proved to be efficient in box girder pre-casting and provides experience for similar girder construction. |
