针对沿海地区混凝土结构开裂后耐久性恶化的问题，研究了荷载裂缝和腐蚀裂缝的修补效果。特别研究了电化学修复技术与传统修复方法相结合的近期和远期效果。修复后，钢筋的腐蚀电位，开裂时间，开裂速度进行了比较，通过不同的修复方法。结果表明，综合修复技术的修复效果明显优于单一修复方法。根据裂纹的特点，设计了复合修复工艺中各步骤的顺序。
To solve the problem of durability deterioration of cracked concrete structures in coastal environments, this study investigates the effect of repairing loading cracks and corrosive cracks. In particular, the immediate and long-term effects of combining electrochemical repair technology with traditional repair methods were studied. After the repair, the corrosion potential of steel bars, cracking duration, and cracking speed obtained by different repair methods were compared. The results showed that the repair effect of the comprehensive repair technique is significantly better than using a single repair method. Based on the characteristics of the cracks, the sequence of each step in the combined repair technique was designed.
