摘要
以保护层厚度、碳化深度、氯离子质量分数、钢筋截面面积损失率、钢筋腐蚀电位作为耐久性指标,采用模糊综合评判法,对氯盐环境中混凝土结构耐久性进行了评估,建立了多层次模糊综合评价模型,并提出了混凝土结构维护管理框架。通过连云港某码头的应用案例,验证了该模型的便捷性与可靠性。
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.
