Abstract: Designing engineering structures in the Arctic zone requires to consider the loads transmitted to the structure construction in connection with collisions with various ice formations: icebergs, ice ridges, stamukhs. The paper considers the use of the grid-characteristic method for modeling the passage of elastic waves in a cross-section of the ice ridge together with its porosity in the consolidated layer and in the lower part of the keel. We propose to use chimeric (overlapped) computational meshes for the describing curvilinear shape of pores filled with air or water. As a result of computer simulation, the direct problem of ultrasound investigation of the ice ridge has solved, velocity vector fields have obtained at various moments in time, including a system of reflections from pores.
Keywords: computer simulation, grid-characteristic method, ice ridges morphometry, ultrasound investigation
