| Abstract: | This paper briefly introduces the choice and design and force analysis of bridge type＆structure size for the prestressed concrete continuous rigid frame bridge. This bridge has adopted the prestressed concrete continuous rigid frame bridge with main span of 85 m. A variable section box girder with single box and single chamber was adopted for the main girder of the main bridge with three - way prestresssing system, rectangular thin - walled hollow pier and bored pile foundation was adopted for substructure of the bridge. Each parts of this bridge meet standard re- quirements by analysing structure for the bridge, and the safety properties are better of this bridge. This paper sum- marizes main points of this bridge design for giving some reference to related technical personnel. |
