Abstract: This paper describes some results of field observations of ice pilings in the Baltic and in the Great Lakes in the United States and Canada. Although the forces exerted on the ice by winds, currents and waves may vary considerably and the structural characteristics of the ice as well as bottom conditions and geometry without doubt play an important role for modes and relative magnitudes of ice pilings, certain common features seem to exist particularly with respect to the geometrical behaviour of pilings. Certain simple experiments in a laboratory tank seem to have confirmed the experience from the field qualitatively regardless of shortcomings in model scaling due to a lack of knowledge on forces and structural abilities of the field ice in various degrees of crushed condition.
