Design of A Pylon Cable-stayed Girder Arch Composite Bridge

With the increasing growing up of bridge building technique,the people’s seeking for the bridge beauty is also more and more.The article introduces the design of a pylon cable-stayed girder arch composite bridge.The superstructure of this bridge is composed of 55 m+35 m+85 m pylon cable-stayed girder arch.Its total length is 175 m.Its structure is the composite one of double-pylon double-plane concrete girder arch.The pylon,girder and arch are consolidated.The main pylon uses 67° steel reinforced concrete pylon with 7 pairs of stayed cables to be arranged in the double-plane fan type.The main girder uses 2.5-m high pre-stressed concrete contour-height box girders.The main arch is the concrete filled tube structure.Its modeling is new and beautiful,and can be referred for the design of urban landscape bridges.
