Project Design And Analysis Research Of Extrodoser Cable-Stayed Bridge

The extradosed cable-stayed bridge is a new kind of bridge type betweenthe continuous beam bridge and the cable-stayed bridge. Based on the NingjiangSonghuajiang Super Large Bridge in Songyuan city, this paper summarized theorigin and development of this kind of bridge, discussed structure characteristicsand key design points of the extradosed cable-stayed bridge. Theoretical analysison the extradosed cable-stayed bridge was carried out by large finite elementsoftwares such as Dr.Bridge and ANSYS and so on, the results showed that theextradosed cable-stayed bridge has lots of advantages such as pleasing shape,flexible span layout, convenient construction, good economical benefit etc.Theprospect of future development trends of the extradosed cable-stayed bridge wasalso put forward.
