IMPROVING QUALITY OF 2D ICE LOAD ESTIMATION ON FREEZED PILES

Abstract

Nowadays a lot of projects are being constructed in the Arctic regions with ice cover. Ports, offshore platforms, satellite stations, lighthouses, and other scientific and environmental constructions are often located in such areas due to economic reasons. Ice loads are important for structure calculation. A number of possible actions from the ice can exist. Ice loads are vitally important; however, there are some gaps in the knowledge and methods. One of the factors to be taken into account is freezing into the ice and developing of ice collars around the structure. This factor leads to an increase of the load from the level ice on the structure. Freezing into the ice is important factor to be considered to improve quality of ice load estimation. The paper presents method to calculate horizontal load on the vertical cylindrical pile by using 2D models in vertical and horizontal plane. Combination of two 2D solutions increases quality of load estimation. The result shows bigger load on structure freezed in the ice comparing to the load on structure in moving ice.
