摘要

The classical ice technology problem of bending and edge failure of the level ice field approaching a rigid obstacle with an inclined front face is considered in a refined setting. The problem is analyzed in quasi-static setting. The exact model with the longitudinal-transverse bending equation for a beam on an elastic foundation is utilized for the ice floe deformation and failure. Semi-analytical solutions are found and compared with known approximations. The corresponding calculation within the refined model demonstrates the increasing loading on the obstacle, as well as the length of broken ice fragment, in comparison with earlier published results.
