A survey showed that more than 40 reinforcement seaport structures and tide barriers had been damaged so that they had only a service period of 7 - 25 years. Therefore, the repair task is difficult. In the present paper, some principles and methods for repairing the reinforced concrete seaport structures are provided and some related technical requirements and materials as well as their preparation and properties are recommended.展开更多
