A continuum model of grounded ice rubble fields is developed in which bulk rubble is treated as a Mohr-Coulomb material at critical equilibrium. The surrounding ice sheet is considered to form a rigid boundary. Approximate stress distributions are obtained using the method of integral relations. Loads on an offshore structure adjacent to a rubble field are related to maximum stresses exerted by the floating ice sheet. The influence of field geometry, grounding resistance, and rubble properties is examined. Peer reviewed: Yes NRC publication: Yes
