Abstract: The vertical forces a floating ice cover exerts on a frozen-in circular pier or pile, due to a rise of the water level, are determined analytically, allowing for partial flooding of the upper surface in the vicinity of the structure. Since, for engineering purposes, the knowledge of the largest possible force is often sufficient, it is assumed that the ice cover responds elastically. To simplify the use of the obtained results, they were evaluated numerically for a range of geometrical and material parameters often encountered in practice and are presented as graphs. It was found that partial flooding has a strong effect on the ice forces and on the ice cover bending moments, provided that the ice strength is sufficiently high to generate them.
