Jinan Jianbang Yellow River main bridge main span 2×300 m cable-stayed bridge with three tow-ers of prestressed concrete beam. In the tower at the tower pier beam consolidation, while Tata by column box girder,the box girder forming the opening section so that the main tower and the tower pier consolida-tion,consolidation formation tower,while the tower of semi-floating system;main girder single box room four inclined web section bridge width 30.5 m,standard cable from the beams and the transverse beams are equipped with stiffening ribs;the tower longitudinal herringbone structure, while the use of single-column structure tower; cable-stayed adoption galvanized parallel wire cable; base using bored pile foundation. Bridge has certain technical breakthroughs and innovations in bridge arrangement, the main beam, the main tower structure design and so on.
