Design of Main Bridge of Caofeidian Bridge Crossing Nachao River

Caofeidian Bridge crossing Nachao River is a partial cable-stayed bridge of 80 m + 128 m+ 80 m three-span double-pylon single-plane prestressed concrete wide-deck with the structural system of pylon-beam consolidation and support constructed on pier.The dynamic and static structural analysis proves that the mechanical performance,durability,anti-wind and anti-earthquake capabilities,and structural stability of the bridge are good and can satisfy the current design specifications.
