| Abstract: | The extra-long bridge across Xijiang river is an important bridge on Guangzhou-Foshan-Jiangmen-Zhuhai intercity railway. In order to determine the most suitable bridge type,this article compares and analyzes 4 bridge schemes,including steel truss arch bridge,steel truss cable-stayed bridge and low tower cable-stayed bridge following the design requirements for safety,functionality,cost-effectiveness and aesthetics based on clearance requirements for one-way and two-way navigation.Finally,the scheme of double 252 m steel truss arch bridge is recommended in view of construction difficulty,landscape effect,navigation condition,engineering cost and other factors. |
