The Influence of the Area Size and the Method of Transverse Load Application to the Ice Cover Surface on the Ice Failure Efficiency

Abstract

Abstract The vertical load application to the ice cover for the purpose of its failure for the passage of the transport vessels in the ice is considered. The energy comparison consumed by the technical vehicles with the volume of the destroyed ice is made when the area size of the application of the failure load increases. The specific work of the external forces (per 1 m3 of the destroyed ice) is shown to significantly decrease with the increasing area of the imposed load. In addition, the additional reduction mechanism of the energy expenditure is shown in case when the failure is performed by the moving distributed load compared with the impact of the load applied on a rigid contour.
