摘　　要：为了缩小钢筋锈蚀速度的测量误差,提出了混凝土结构中钢筋锈蚀速度快速测量方法。采用钢筋锈蚀反应过程的表达式,对钢筋锈蚀电化学反应过程进行了分析,根据锈蚀量和锈蚀电流的定量关系,计算出单位面积钢筋腐蚀反应的质量,并根据锈蚀速率的计算公式,建立了钢筋腐蚀速度的测量模型,实现了混凝土结构中钢筋锈蚀速度的测量。实验结果表明,提出的测量方法可以缩小测量误差。In order to reduce the measurement error of steel corrosion rate,a rapid measurement method of steel corrosion rate in concrete structures is proposed.Using the expression of the steel corrosion reaction process,the electrochemical reaction process of steel corrosion was analyzed.According to the quantitative relationship between the amount of corrosion and the corrosion current,the quality of the steel corrosion reaction per unit area was calculated.And according to the calculation formula of the corrosion rate,the measurement model of the steel corrosion rate is established,and the measurement of the steel corrosion rate in the concrete structure is realized.The experimental results show that the proposed measurement method can reduce the measurement error.
