| Abstract: |
In this research, focusing on the phenomenon that the general part of the suspension bridge main cable located in the mountainous/plain area corrodes unevenly toward the upper surface of the cable and aims to elucidate the corrosion mechanism. As a result of investigating of corrosion environment and a corrosion acceleration test using a simulated rope, it was found that there is a period on the rope surface where the corrosion rate of galvanization reaches the highest temperature range. It was also found that the water that tends to remain on the upper surface of the rope is heated during the day due to rainfall and dew condensation, and that only the upper surface may be unevenly corroded. |
