Full-course stress self-sensing FRP anchor rod based on coaxial strain sensing cable

The invention relates to a full-course stress self-sensing FRP (Fiber Reinforce Plastic) anchor rod based on a coaxial strain sensing cable, which comprises the coaxial strain sensing cable, an FRP wrapping layer and an anchor head, and is characterized in that the coaxial strain sensing cable is extruded and deformed by at least more than two metal thin-walled tubes sleeved on the coaxial cable at a certain interval; and the head end and the tail end of the coaxial cable are respectively connected with a radio frequency coaxial connector and a 50-ohm terminal load. The coaxial strain sensing cable is implanted into the central axis of the FRP wrapping layer, the coaxial strain sensing cable and the FRP wrapping layer are organically solidified to form an FRP rod body, the head end of the coaxial strain sensing cable is led out from one side of the rod body, the tail end of the coaxial strain sensing cable is wrapped in the rod body, and the FRP rod body and the anchor head are assembled to form the FRP ancho
