| Abstract: | Because the cast-in-place side-span segment of continuous girder bridge has the larger length, it has the higher requirements for bracket strength. In combination with the practical engineering case of Nanchong Jialing River Bridge in Lan-Yu Railway, the article carded out the optimization design on the bracket program of its 60m continuous girder side-span cast-in-place segments,and made the selection analysis compared to the original design program from both technical and benefit aspects. |
