AbstractLaboratory tests were conducted to investigate the effects of displacement rate, ice thickness and pile diameter on the adhesion of a saline ice sheet to wooden piles. The ice used was representative of naturally formed columnar-grained sea ice. Cylindrical piles having diameters between 30 and 145 mm were pulled up at constant nominal displacement rates between 1.5X10-4 and 7.8X10-2 mm/sec, for ice thicknesses from 58 to 170 mm. The failure mode, either shear at the pile-ice interface or flexural in the ice was observed to depend upon the test parameters. The adhesion strength was observed to increase with increasing pile displacement rate, increasing ice thickness and decreasing pile diameter. The adhesion strength of saline ice was found to be smaller by a factor of at least 3.5 than that of fresh-water columnar- grained ice measured earlier under similar conditions.
