Zusammenfassung:The invention relates to an enhanced bearing plate for a tension-compression composite anchor rod. The enhanced bearing plate for the tension-compression composite anchor rod includes a bearing plate,a grouting pipe perforation hole and rib perforation holes are formed in the bearing plate, a plurality of rib connecting grooves are formed in one end of the bearing plate in the axial direction, internal screw threads are arranged in the rib connecting grooves, the rib connecting grooves further include a plurality of reinforcing ribs, and the multiple reinforcing ribs are connected to the ribconnecting grooves corresponding to threads. The invention further provides an anchor rod adopting the enhanced bearing plate. According to the enhanced bearing plate for the tension-compression composite anchor rod, the compression bearing capacity of a grouting body in front of the bearing plate can be significantly improved, and the problem of insufficient compression bearing capacity of the grouting body with a large-t
