| Abstract: | Nielsen system concrete-filled steel tube rigid tied bar arch bridge could meet the meets of heavy haul railway and high speed with large longitudinal stiffness superior dynamic performance. The bridge adopted the construction method of arch first and beam and cantilever construction technique of tied girder. The assemble of arc-rib , arch segment lifting, cast-in-place and cantilever construction of tied girder were studies that the construction followed the design rule to meet the requirements of the design and construction code. |
