The invention provides a compound prestressed anchor cable capable of improving anti-shear performance of an anchorage structure, and belongs to the technical field of rock
mass reinforcing. The anchor cable comprises a guiding cap, steel strands, a tensioner ring, a tightening ring, a sleeve and a grouting
pipe; the sleeve is arranged nearby a sliding face or a potential sliding face, thus, the anti-shear effect of the anchorage structure can be effectively improved, and the defect that deformation is severe and even a slope is instable and is damaged due to the fact that a traditional prestressed anchor cable is short of the anti-
shear capacity is overcome. Compared with the traditional prestressed anchor cable, according to the compound prestressed anchor cable, the arrangement distance between anchor cables can be increased, and meanwhile, the number of the anchor cables is decreased, so that related materials, time and fund investment are saved. The compound prestressed anchor cable capable of improving the anti-shear performance of the anchorage structure has the prominent advantages that the process is simple,
operability is high, resources are saved, and the position of the anti-shear structure is controllable.
