doi:10.3969/j.issn.1674-0696.2015.01.06

Abstract

Abstract: The factors which influenced the cable steel wires corrosion was classified into two main kinds,that is,external enviroment factors and the own state of steel wires.And other influence factors,such as humidity,temperature,atmospheric pollutants,wire tension,initial loss and the main cable bendine were elaborated in detail.Based on the obtained research results,the influence mechanism of above factors on the cable steel wires corrosion and the corrosion rate was analyzed in detail.And then the main factors influencing the cable steel wires corrosion were obtained.Therefore,the multi-wrre-group corrosion test corrosion test considering the interaction between various factors was proposed,which was more appropriate to simulate the actual main cable corrosion process.

Key words: bridge engineering, main cable of suspension bridge, high-strength galvanized steel wire, corrosion rate

摘要： 影响钢丝腐蚀的众多因素，分为外界环境影响因素和钢丝自身状态两大类，详细阐述了湿度、温度、大气污染物以及钢丝拉力、初期损失、主缆弯曲等各影响因素已有的实验研究成果，深入分析了上述因素对钢丝腐蚀产生影响的机理及其对腐蚀速率的影响。在得到对钢丝腐蚀产生影响的重要因素基础上，提出了需综合考虑各因素间的相互作用的多钢丝组的腐蚀实验，以达到更贴切地模拟主缆实际腐蚀过程的目的。
