Ice loads acting on structures to which ice sheets are adfrozen during flooding and measures to decrease ice loads

摘要

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.
