Taking the thickness of protective layer,carbonation depth,chloride ion mass fraction,steel bar cross-sectional area loss rate and steel bar corrosion potential as durability indexes,the durability of concrete structures in chloride environment was evaluated by fuzzy comprehensive evaluation method.A multi-level fuzzy comprehensive evaluation model was established,and a concrete structure maintenance management framework was proposed.Through the application case of a wharf in Lianyungang,the convenience and reliability of the model were verified.
