摘要
通过三类１８０根锈蚀试件的观察和２５８根钢筋的破型试验分析，提出了对混凝土构件中钢筋锈蚀程度进行宏观、定量评定和预测的方法，得出了钢筋锈蚀与纵裂宽度、保护层厚度、钢筋直径和混凝土强度之间的关系公式。
Macro, quantitative and predictive methods for studying corrosive degrees of rebars in concrete members are proposed by observing 180 specimens of three types and testing 258 broken rebars; a related expression between corrosion of rebar and width of longitudinal crack,cover thickness, diameter of rebar and concrete strength is obtained, so a scientific basis is provided for the durability estimation and the reliability appraisal of concrete structures.
