Abstract As the main force transfer structure of the beam in bridge, the cable must has enough service safety. In view of the corrosion damage caused by HDPE sheath breakage in practical engineering, defect machining of the cable and the impressed current cathodic protection (ICCP) experiment was carried out to study the Cl^- diffusion behavior and spatial diffusion model considering ICCP. The results show that ICCP can effectively inhibit the corrosion process of the cable, the average Cl^- diffusion coefficient decreases significantly. The corrosion risk and corrosion degree of the cable increase with the development of breakage, and decrease with the output of protection potential. Based on Fick law, the Cl^- spatial diffusion model considering both ICCP and initial breakage was established, and the diffusion blocking coefficient and breakage influence coefficient was used to revise the model. The model shows that the Cl^- diffusion blocking effect of ICCP is significant, and the breakage influence coefficient is positively correlated with the breakage size.

Key words： bridge engineering cable impressed current cathodic protection (ICCP) corrosion experiment Cl^- diffusion
