Prestressed concrete pipe pile is widely used in coastal areas, but the penetration of chloride ions affects the durability of PHC pile. The damage of PHC piles, which will reduce the seismic capacity of structures,is difficult to be found and repaired, so anti-corrosion measures for the PHC pile shall be considered. In view of the characteristics of structure and construction of the PHC pile, several anti-corrosion measures are introduced for the PHC pile, which are suitable for various conditions. It may serve as a reference for the project of PHC piles with a requirement of anti-corrosion.
