为了对海水环境下CFRP-混凝土界面性能进行研究，采用42个CFRP片材进行了CFRP材料物理力学性能试验，采用72个混凝土单剪试件对海水环境下CFRP-混凝土界面黏结性能进行试验。结果表明：CFRP材料的耐久性良好，长时间的海水腐蚀对CFRP材料的物理性能没有太大影响；CFRP-混凝土黏结强度随腐蚀时间增加而降低；长时间海水腐蚀对界面延性有不利影响，对界面应变发展规律和黏结滑移关系没有明显影响。

To investigate the durability of carbon fiber reinforced polymer(CFRP) sheets and the bond behavior between CFRP-con-crete interface in marine environment 42 CFRP specimens and 72 single shear test specimens were conducted.Results indicated that the durability of the CFRP sheets was so excellent that long-term seawater corrosion has little influence on it;bond strength between concrete and CFRP decreased with the increase of erosion time;long-term seawater corrosion has an adverse effect on the ductility of CFRP-con-crete interface and has no significant effect on the development of strain and the bond-slip constitutive relationship.
