摘要
PHC管桩在沿海地区应用广泛,然而氯离子的渗透会影响PHC管桩的耐久性。PHC管桩受损后难以发现和修复,影响结构物抗震能力,因此应考虑对PHC桩采取防腐蚀措施。针对PHC管桩构造和施工特点,介绍多种工况下,适合于PHC管桩各个部位的防腐蚀措施,为有防腐要求的PHC管桩施工项目提供参考。
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.
