The invention relates to a composite anchoring structure and a cable-stayed-suspension cooperative system steel truss girder bridge, which relates to the field of bridge sling anchoring construction. The composite anchoring structure comprises a composite anchoring and pulling plate fixedly connected with the bridge, a stay cable anchoring structure fixedly arranged at one end of the composite anchoring and pulling plate and used for anchoring an inclined stay cable connected with the bridge, and a vertical sling anchoring structure fixedly arranged at the other end of the composite anchoring and pulling plate and used for anchoring a vertical sling connected with the bridge. Due to the fact that the vertical sling is connected with the vertical sling anchoring structure, the inclined stay cable is connected with the stay cable anchoring structure, the vertical sling anchoring structure and the stay cable anchoring structure are both arranged on the composite anchoring and pulling plate, the composite anchoring and pulling plate is fixedly connected with the bridge, and finally the vertical sling and the inclined stray cable are connected to one point of the bridge. And the force transmission effect between the inclined stay cable and the sling and the bridge is obviously improved, so that the stress of the bridge is more stable, and the safety coefficient is effectively improved.
Description
technical field [0001] The application relates to the field of bridge suspension anchorage construction, in particular to a composite anchorage structure and a steel truss bridge of a cable-stayed-suspension cooperative system. Background technique [0002] Cable-stayed bridges and suspension bridges are the two most commonly used types of long-span and super-long-span bridges. As the requirements for bridge structure safety and construction technology are getting higher and higher, cable-stayed-suspension cooperative system bridges are more and more used in super-long-span bridges because of their characteristics of combining the advantages of cable-stayed bridges and suspension bridges. [0003] In related technologies, cable-beam anchorage points of cable-stayed-suspension cooperative system bridges are usually arranged at equal intervals along the longitudinal direction of the bridge, and a certain length of overlapping area between cable-stayed cables and slings is set ...
