东莞水道大桥构造设计关键技术

On Key Technologies of Structure Design of Dongguan Shuidao Bridge

东莞水道大桥是东莞五环路西环段上的一座特大桥。主桥采用三孔50 m+280 m+50 m的中承式钢管混凝土系杆拱桥。介绍了主桥拱肋、水平系杆、吊杆、桥面系构造设计中的主要技术特点和技术创新,期望为今后相关的工程设计提供参考。

Taking Dongguan Shuidao Bridge for example in this paper,it is a super-large bridge over the west ring section of the Fifth-ring Rd.in Dongguan with the half through steel concrete tied arch,main bridge of three holes 50 m +280 m +50 m.Several main technology characters and creations are introduced including arch rib,horizontal tie bar,suspender and bridge deck system structure design,etc.,which can provide references for the similar projects in the future.
