摘要

本研究调查了缆索支撑桥梁中使用的高强度镀锌钢丝的“锈色分布率”、“腐蚀表面形状”和“疲劳强度”之间的关系。该研究利用数字图像颜色分析系统对铁锈颜色分布率进行分类,并根据分布率对腐蚀程度进行分类。从分类的腐蚀水平可以直观、定量地理解横截面损失率与腐蚀深度趋势之间的关系。研究发现,在本研究中设定的腐蚀水平下,试样的疲劳和拉伸强度等于或高于新线材的疲劳和抗拉强度。然而,不能排除由于试样数量少或腐蚀进度不足而产生变化的可能性。

Correlation between corrosion level and fatigue strength of high-strength galvanized steel wires used for suspension bridge cables
This study investigated the relationship between “rust color distribution ratio,” “corrosion surface shape,” and “fatigue strength” of high-strength galvanized steel wires used in cable supported bridges. The study utilized a digital image color analysis system to classify the rust color distribution rate and categorize corrosion levels based on the distribution ratio. The relationship between cross-sectional loss rate and corrosion depth tendency was visually and quantitatively comprehended from the categorized corrosion levels. The study found that fatigue and tensile strengths of the specimens from the corrosion levels set in this study were equivalent to or higher than those of new wires. However, the possibility of variations due to the small number of specimens or insufficient corrosion progress cannot be ruled out.
