我们在本文中的目的是介绍一组将钢筋腐蚀的分布与此类腐蚀导致的覆盖层裂缝宽度联系起来的关系。这项工作基于两根梁的纵向钢筋在 14 和 17 年的自然腐蚀期间获得的实验结果。我们首先将这些实验结果与连接裂纹宽度和攻击渗透的现有模型进行比较。注意到此类模型只能部分预测实际实验数据，我们提出了一种使用钢筋横截面损失参数的新模型。 (C) 2003 Elsevier Ltd. 保留所有权利。
Our aim in this paper is to introduce a set of relationships linking the distribution of reinforcement corrosion and the width of cover crack that results from such corrosion. This work is based on experimental results obtained on the longitudinal reinforcements of two beams naturally corroded over periods of 14 and 17 years. We first compared these experimental results with existing models linking crack width and attack penetration. Noting that such models only partially predict actual experimental data, we put forward a new model using the parameter of reinforcement cross-section loss. (C) 2003 Elsevier Ltd. All rights reserved.
