| Abstract: | Simply supported beam bridge turning into continuous beam bridge combines the advantages ofsimply supported beam bridge and continuous beam bridge. The technology of its construction is as follows. First- ly, set the temporary supports. Secondly, put precast beams on the temporary supports. Then, pour concrete in the seams of the adjacent beams and stretch prestressed reinforcement in hogging moment area. Lastly, dismantle the temporary supports. Moreover, the winter construction in Xinjiang should be considered. |
