ICE LOADS ACTING ON STRUCTURES TO WHICH ICE SHEETS ARE ADFROZEN DURING FLOODING AND MEASURES TO INCREASE ICE LOADS

In frozen sea waters, when the water level rises with the ice sheet adfrozen to a structure, sea water gathers on the ice sheet near the structures. This phenomenon is called flooding and arises when sea water rises to the ice surface through brine channels and cracks of the ice sheet. Under these conditions, where flooding occurs, the ice sheet functions as a bearing and is affected by elasticity. However, under the conditions where flooding has no influence, the sheet is affected only by buoyancy. In this paper, the authors logically clarified the upward vertical ice loads acting on the structure due to the rise of the water level when flooding occurs. Also, a comparison was made of ice loads when flooding occurs and when it does not. They have also systematically proven the method to gradually decrease ice loads caused by the change in the water level because ice loads are smaller when flooding occurs. In addition, it has been made clear by experiments, the adfreeze bond strength between various materials and the ice sheet, which is required for the calculation of ice loads caused by the change in the water level.
