Abstract
In the outer coastal zones, where wave conditions are severe, steel-pipe piles often undergo abrasion due to the collision of sand particles. The abrasion characteristics of steel-pipe piles were clarified from the results of full-scale experiments. The abrasion rate of steel-pipe piles was found to be approximately proportional to the second power of the amplitude of flow velocity. The larger the ratio of sand particle diameter to pile diameter was, the higher was the abrasion rate. As the collision energy of sand particles obtained by numerical analysis was nearly proportional to the measured abrasion rate, it was considered that the abrasion rate can be estimated from the collision energy.
