摘要：

结合现场试验,阐述了高桩码头延寿技术的技术原理和施工工艺。结果表明,该技术可有效脱除混凝土内的氯离子并使有效阻锈剂基团快速渗入到混凝土内部,使钢筋恢复钝化而停止腐蚀,从而显著延长码头使用寿命。

According to the field experiments,the technical principle and construction technology of prolonging life technology for a high-piled wharf were expounded.The results show that chlorine ion would be moved away from the RC structure as inhibitor would be moved to the steel bars rapidly,which made the steel bars passivated again by this technology,thus it could prolong the service life of a long piled wharf effectively.
