摘　　要：海洋环境的复杂性,特别是污损生物的长期附着作用,会对海工钢筋混凝土工程造成严重腐蚀。本文结合国内外现有的研究结果以及中科院海洋研究所早期的污损生物腐蚀相关实际工程研究,从海水/混凝土界面污损生物群落的形成,污损生物对混凝土表面涂层的破坏、对混凝土本体和钢筋可能的破坏过程等几方面,对污损生物附着和腐蚀作用机制进行深入探讨。海洋污损生物的群落附着机制复杂,对钢筋混凝土结构的腐蚀过程也呈多样化,有待深入研究。Due to the complexity of the marine environment,especially the long-term attachment of fouling organisms,the durability of concrete under the marine environment faces a great challenge.In this paper,combined with existing research results at home and abroad,and early corrosion engineering research conducted by the Chinese Academy of Sciences Institute of marine fouling organisms,four points of the formation of fouling communities on the seawater/concrete interface,including the destruction to the coating of concrete surface by the fouling organisms,the possible progress of destruction to the concrete by the fouling organisms,the possible progress of destruction to the steel bar by the fouling organisms,and the mechanism of biofouling and corrosion are discussed.According to the study results above,we know that the attachment mechanism of the ocean biofouling and the corrosion mechanism are complex that further research is needed.
