This paper points out the structural defects of the cable body through the analysis of the main structural characteristics of the pressure distributed anchor cable, and further puts forward the application of the new technology to improve the structure of the prestressed anchor cable, and overcome the inherent defects of the original pressure distributed anchor cable structure. Under the same anchoring mechanism, the author proposes that the anchorage anchorage point can be designed according to the anchoring needs, so that the prestressed anchor cable can have a certain stress release function, which can release the excessive deformation of the anchored rock and soil mass, effectively protect the stress level of the anchor cable, and improve the safety and durability of the anchor cable. Through engineering application, it is proved that the structure is reasonable, the anchorage is convenient, and the reliability of construction is greatly improved.
