Ice scouring is a phenomenon which occurs when moves in contact with seabed. It has been reported tohave caused damage to communication cables and water intake pipelines. Therefore, it will be veryi mportant to estimate rational maximum scour depth due to complicate behavior of ice, and will also bevery important to evaluate forces acting on sea bed and stress that is transmitted via the seabed andd eformation of soil.
We have developed the rational experimental device system as compared to previous device system. Under the renewal conditions, we conducted a lot of test series, and werevealed relationships between iceforces and beha vior of ice, variations of its behavior due to varies condition (attack angle, travellingvelocity). And we also revealed the probability distribution of some random variable under the same experimental condition.
