Vertical stresses from grounded ice ridges, rubble and pads in the Beaufort Sea
Resistance to lateral loading of grounded ice, a critical design issue for offshore installations, is a function of the friction coefficient at the ice/seabed interface and the vertical stress exerted by the ice onto the seabed. In order to assess the latter, a range for each of the five basic param...
