Combined cable-girder anchoring structure of pre-stressed concrete cable-stayed bridge top

A combined cable-girder anchoring structure of the pre-stressed concrete cable-stayed bridge top aims to directly transmit the cable force of a cable-stayed cable to the center of a web so as to remove the transverse eccentric bending moment of the cable force on the web. The combined cable-girder anchoring structure comprises a box girder and a cable-stayed cable (40) with one end anchored on the box girder. Post-cast concrete anchor blocks (20) are arranged at the top of webs (10) of the girder box at the corresponding positions of the girder sections, pre-stressed steel beams (30) are pre-buried in the webs (10) and the post-cast concrete anchor blocks (20), and the pre-stressed steel beams (30) connect the webs (10) and the post-cast concrete anchor blocks (20) after one ends of the steel beams are tensioned at one ends of the post-cast concrete anchor blocks (20) to form a stressed whole body. Combined anchor bearing plates are fixedly pre-buried in the post-cast concrete anchor blocks (20), and one end of the cable-stayed cable (40) is anchored on the combined anchor bearing plates.
