Abstract: A series of laboratory experiments were carried out in the Ice Engineering Facility test basin at Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire, U. S. A. The aim was to measure maximum induced vertical ice forces on piles during water level changes, and to study the effect of the amplitude and frequency of the changes on the induced forces in both a short-term and a long-term perspective. An additional aim was to study the group effects in clusters of piles. Only the first cycle of the water level fluctuation is considered in this paper. The test results show a considerable discrepancy between measured forces and forces predicted by theory. The possible reasons for the discrepancies are discussed thoroughly. The use of urea model ice and the use of cantilever beam tests for determination of flexural strength are questioned.
