| Résumé | This paper presents a discussion of the ice failure modes that have been observed on wide caisson structures in the Arctic. These failure modes include ice bending (flexure), buckling, mixed mode, crushing, splitting and creep. It was found that bending and buckling are observed only for thinner ice whereas mixed mode, crushing and splitting are observed for all thicknesses of first-year ice with moving ice sheets. Creep is observed only with low loading rates. Analysis shows that the line loads increase with the ice thickness in a linear manner for ice crushing. This behavior appears to continue for thicker, Old Ice. The scatter in data is large with mixed mode and there is no clear trend of line load with ice thickness. There is insufficient information to determine the thickness dependence of bending, buckling, splitting or creep. |
