Grounded rubble fields adjacent to offshore structures
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. Loa...

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. Un modèle continu de champs d'amas de glace reposant sur le fond est élaboré. Dans ce modèle, l'ensemble des blocs de glace est traité comme un matériau de Mohr-Coulomb en équilibre critique et la nappe de glace environnante constitue une frontière rigide. On obtient la distribution approximative des contraintes à partir de la méthode des relations intégrales. Les charges sur un ouvrage construit au large des côtes et adjacent au champs d'amas de glace, sont exprimées en fonction des contraintes maximales exercées par la nappe de glace flottante.
