Abstract
A Carbon Fiber Reinforced Polymer (CFRP) concrete composite component with partitioned cathodic protection and an operation and maintenance method thereof are provided. The composite component includes multiple longitudinal reinforcements, in which a first area, a second area and a third area corresponding to underwater, splash and atmosphere are arranged along an extending direction of each longitudinal reinforcement, respectively; a first spiral rib, which is wound around the multiple longitudinal reinforcements in the first area; a second spiral rib, which is wound around the multiple longitudinal reinforcements in the second area; a third spiral rib, which is wound around the multiple longitudinal reinforcements in the third area; a concrete; a power supply, where the first spiral rib, the second spiral rib and the third spiral rib are connected with a positive electrode of the power supply, and the longitudinal reinforcement is connected with a negative electrode of the power supply.
