We developed a numerical method using 2-D DEM to simulate the interaction between ice floes and structures, which will be needed to consider countermeasures against the deterioration of marine structures due to contact with sea ice floes. The validity of the numerical method was made by comparison with observation results concerning contact forces by load cells embedded in the channel wall in the 2nd entrance of Lake Saloma. The numerical calculation results not only agreed well with the

Thus, this method was found to be very useful as one of general analysis tools to estimate interaction between ice floes and structures. 2 1 2 2
