| Abstract: | Aixi Lake Bridge is a 30 m + 108 m + 30 m three-span continuous extroversive four-plane through steel box bowstring landscape arch bridge.The structure of main bridge is composed of orthogonal anisotropic plate steel box beam,steel arch rib,parallel steel wire unit suspender and prestressed steel strand bowstring.Various mechanics performances,wide and earthquake resistances and structure stability of this bridge all satisfy the current design standards after the analysis of structure stress. |
