Research on Scheme of Wulongjiang Railway Bridge on Fuzhou-Xiamen PDL
摘要
Abstract
Wulongjiang extra-long railway bridge on Fuzhou-Xiamen PDL traversing Wulongjiang river is the key project of the whole line,and the construction conditions and boundaries for span arrangement on the bridge site are complex.In order to determine the most suitable bridge type,comparison and analysis are conducted of the two schemes of bridge type,including the cable-stayed bridge and the steel truss girder suspension bridge following design requirements for safety,functionality,cost-effectiveness and aesthetics.It is concluded that the hybrid girder cable-stayed bridge with two unequal-height pylons(spans of(72+109+432+56+56)m)is the most appropriate one to be recommended.The bridge will be the first long-span hybrid girder cable-stayed bridge with two unequal-height pylons for four railway lines in the world after completion.关键词
