Abstract: The investigation of the pressure of floating ice fields against piles started on the assumption that the maximum pressure of ice was limited by its compressive strength. Therefore this strength was first of all ascertained by laboratory tests on cubes of several ice types. The results factored in the influence of temperature, velocity of deformation and direction of pressure on the cubic strength. In order to employ these laboratory results for the calculation of structures, a relationship between the strength in laboratory tests and in nature was derived by measuring the pressure of floating ice-fields on a pile of a bridge, which crosses the tidal estuary of the EIDER River. The investigation leads to an equation, which allows the calculation of ice pressure against piles.
