This paper proposed a new probabilistic Bi-plane cellular automaton (CA) model to simulate the localized pitting corrosion of stayed cables. The CA model introduced chloride ions and their evolution rules to take into account the local acidification catalysis is in microscopic scale. Besides, a Monte Carlo approach is adopted to analyze the statistical properties of corrosion pit size and their variation with respect to time. The proposed CA model is confirmed by several published experiments on pitting corrosion. It is capable to reproduce the experimental observations and enlarge the sample space for subsequent mechanical analysis.

基于双平面元胞自动机的电缆线坑蚀过程的蒙特卡罗模拟方法

本文提出了一种新的概率双平面元胞自动机（CA）模型来模拟斜拉电缆的局部点蚀。CA模型引入了氯离子及其演变规律，以考虑微观尺度上的局部酸化催化作用。此外，采用蒙特卡洛方法分析腐蚀坑尺寸的统计特性及其随时间的变化。所提出的CA模型已通过一些已发表的点蚀实验得到了证实。它能够复制实验观察结果并扩大样本空间，以用于后续的机械分析。
