氯盐环境下钢筋蚀坑深度时变模型

摘要

Based on Fick’s second law,the paper studies time-varying property of chloride expansion coefficient and time-varying model of corro-sion pit depth under local corrosion,and explores multiple influencing factors sensitivity of time-varying model of steel corroded pit depth,with a view to find out the changing law of steel corroded pit depth under chloride environment.%基于Fick第二定律，对氯离子扩散系数时变性、局部锈蚀时的蚀坑深度时变模型进行了研究，同时探讨了钢筋蚀坑深度时变模型的多重影响因素的敏感性，以得出氯盐环境下钢筋蚀坑深度的变化规律。
