摘　　要：Carbon fiber reinforced polymer(CFRP)can be applied for bridge cables due to its excellent properties.As the important load-bearing structural component,real-time force monitoring of the CFRP cable is required.This paper presents a new smart CFRP cable that combines the self-sensing rods with embedded sensors and the anchorage system using extrusion technology.By embedding optical fiber(OF)and coaxial cable Fabry-Perot interferometer(CCFPI)into CFRP rods respectively,two types of self-sensing rods(CFRP-OF rod and CFRP-CCFPI rod)were fabricated.A new anchorage unit using an extrusion process was proposed as a basic component of smart CFRP cables.Anchorage units holding a CFRP-OF rod and a CFRP-CCFPI rod were tested to obtain their sensing and mechanical properties.Three ancho-rage units were assembled to form a smart CFRP cable with self-sensing functionality.A verification test was carried out to confirm the capabil-ity of monitoring the cable force.The test results demonstrate that the smart CFRP cable composed of multiple anchorage units has good potential in bridge engineering.
