| Abstract: | The construction of fixing steel box girder block No. 0 of the main bridge of Shanghai Changjiang River Bridge without using cross beam had no precedent to go by. After calculation and analysis of the key loading cases of the construction, the technique for fixing of pylon and girder was carefully considered and the innovation of the Preloading and Self-Balanced Fixing System was applied to the fixing in the vertical direction. The technique as presented in the paper may provide reference for the construction of similar bridge works. |
