The behaviour of friction piles in ice and ice-rich soils

Abstract

A comprehensive review of long-term creep tests on ice has been undertaken and a flow law for ice has been proposed. Creep tests on ice-rich soils have also been reviewed, and it is concluded that the flow law for ice constitutes an upper bound to these test data. Using this flow law, pile velocities in ice and ice-rich soils have been predicted and the predictions are shown to be in good agreement with available long-term creep data for piles in ice and ice-rich soils.
