| Abstract: | The continuous girder structure with spans(75 135 135 75) m is currently the longest span continuous girder for passenger dedicated railways with running speed 350 km/h and is also one of the control works of Guangzhou-Shenzhen-Hongkong Passenger Dedicated Railway Project.In this paper,the structural formation features,internal force analysis,prestressing system,prestressing strand layout and dynamic analysis of the continuous box girder structure are presented.The presentations in the paper provide helpful reference for the design of long span bridges for high speed railways. |
