Abstract: Serious damage has occurred to coastal structures and training levees made of steel-sheetpile-type seawalls on the Sea of Okhotsk, even where there has been only slight horizontal movement of sea ice. One reason for this damage is the action of sea ice, and wear, abrasion, deformation and so on of steel sheet piles have been observed on the surfaces of steel sheet piles. If sea ice can remove rust layers from steel surfaces, further corrosion during ice-free periods will promote further damage. Therefore, larger wear of steel in ice-infested seas than in ice-free seas should be taken into account in the design of these steel structures. In this study, sliding wear tests were conducted in a cold room to evaluate conditions in which rust layers are removed from steel surfaces. Especially, the effect of sand (inclusion& grain size) inside sea ice on wear of corroded steel is evaluated with constant ice temperature and contact pressure, since sand is naturally included inside sea ice.
