Abstract： This paper combines large-diameter CFRP cable with ultra-high performance concrete， gives full play to the characteristics of light weight， high strength and corrosion resistance of carbon fiber and the advantages of high durability of ultra-high performance concrete， adopts composite anchoring technology， develops supporting anchors， determines the anchoring process， and carries out static load and fatigue tests on Φ12 single-hole CFRP cable anchoring unit and porous CFRP cable anchoring cable respectively. The reliability of the anchorage technique is proved.
