Abstract: This paper presents results of 2D numerical simulations of ice failure and pile-up process against an inclined structure. The process is simulated with a two dimensional combined finite discrete element method (2D FEM-DEM). In the method, a level ice sheet and its fracture are modelled by using the finite element method. The contact forces betwee n the colliding ice blocks broken off the level ice sheet are calculated by using the discrete element method. Results of simulations concerning pile pro files, porosities and ice block siz es in the rubble pile are presented and compared to those measured from ice ridges in the field. In add ition, the failure modes of the intact ice sheet during the rubble pile build up process are examined.
