摘　　要：利用腐蚀电化学原理，建立了一般大气环境混凝土中钢筋锈蚀量的预测模型，结合工程调查给出了模型中参数的具体确定方法，进一步考虑环境相对湿度和钢筋表面水膜对氧的吸收能力，对公式进行修正，并分析了钢筋锈蚀量与混凝土强度，保护层厚度，钢筋直径和锈蚀时间的关系。Based on the theory of corrosion electochemistry, predeterminate of steel corrosion in concrete under common air environment is established, and detailed method to determine model's parameters is given by using investigation results of engineerings. Formulas are corrected concerning with air relative humidity and ability to absorb oxygen for water membrane of steel surface. The author analyzes relationship of steel corrosion extent and concrete strength, cover thick, steel diameter and corrosion time.
