大跨桥梁缆索钢丝腐蚀速率的试验研究
Corrosion Rate Test of Cable Wires of Large Span Bridge
摘要
Abstract
In order to explore the corrosion law of large span bridge cables,cylindrical corrosion electrodes were prepared according to the actual corrosion state of bridge cable wires,and the electrochemical corrosion rate of the high strength-steel wires were investigated by orthogonal experiment design and electrochemical experiments. The influence of temperature,salinity,pH value, and their interaction on steel corrosion rate were studied through intuitive analysis and variance analysis of the test results. The result shows that the environmental impact factors can be ordered descendingly by their importance in affecting the corrosion rate of cable wires as NaCl concentration > temperature> interaction between temperature and pH value > pH value > interaction between temperature and NaCl concentration > interaction between NaCl concentration and pH value. In addition,temperature and NaCl concentration bear a monotonic relationship with the corrosion rate and pH value bears a nonmonotonic relationship with the corrosion rate.关键词
