摘要
为了准确评估混凝土碳化深度和钢筋锈蚀程度,综述了现有的一些混凝土碳化模型和钢筋锈蚀模型的特点,以工程实测数据为证,重点比较了各个模型预测值与实测值之间的差异,并讨论了该差异大小不同的原因,最后建议了不同模型的适用条件。结果可以为混凝土结构耐久性评估工作提供参考。
In order to accurately assess the concrete carbonation depth and rebar corrosion degree,the features of some carbonation model and rebar corrosion model were summarized.Based on the filed test data, the errors between different models and the reason were compared and analyzed. Then applicable condition of different models were proposed.The results can provide reference for the assessment of concrete structures durability.
