混凝土结构耐久性退化数学模型及评述

On Mathematical Models of Durability Degradation of Concrete Structures

混凝土结构耐久性退化数学模型是分析结构性能劣化过程的基本模型。通过分析已有的混凝土碳化、氯离子侵蚀、钢筋锈蚀和冻融破坏等数学预测模型,给出了当前较为完善的退化模型。最后评述了现有研究存在的不足,也对混凝土桥梁耐久性的研究提出了建议。

Mathematical models on durability degradation of concrete structures are the basis of analyzing the deteriorating process of structural behavior. By analyzing the existing models on concrete carbonation, chloride ion corrosion, reinforcement erosion and freeze-thaw damage, etc., some improved models of degradation are given. Described hereby are some deficiencies in current study and also proposals therefor.
