摘　　要：钢筋混凝土构造物暴露在海洋环境中容易出现钢筋锈蚀引起的耐久性破损,导致结构物整体加速腐蚀破坏,因此及时对破损钢筋混凝土构造物进行维修对延长结构使用寿命具有重要意义。海工钢筋混凝土构造物维修除了考虑修补材料一般性能以外还须考虑施工环境和耐久性问题。随着材料科技和施工技术的发展,人们研发出了适用于海洋环境的各种修补材料和施工工艺,能适用于不同的施工环境和施工要求。系统介绍和分析了目前常用于海工构造物维修中的一些维修新技术。The reinforced concrete structure which exposes in the marine environment easily appears damage due to corrosion of reinforced bars,leading to accelerated corrosion damage of the whole structure.Thus it is important to repair the damaged reinforced concrete structures timely and prolong the service life of the structure.For the repair of marine R.C.structures,both the general performance of the repairing materials and the construction environment and matter of durability shall be considered.With the development of material technology and construction technology,various kinds of repairing materials and construction technology adapting to different marine environments have been developed.Some new repairing technologies commonly used for marine structures are analyzed in this paper.
