This manuscript investigates the deformation of ice layers under a moving block, focusing on the theoretical framework and mathematical models that describe the mechanical and thermal properties of ice and its interaction with underlying water. It delves into the formulation of the problem, discussing the assumptions and conditions applied, such as neglecting gravitational forces and considering ice's mechanical properties to be functions of spatial coordinates. The document extensively reviews ice mechanical properties, the application of Lamé's equations for an inhomogeneous medium, and the International Equation of State of Seawater to establish a comprehensive model. It further explores linear acoustics in perfect fluids, employing Fourier transform techniques for analytical solutions. The study aims to contribute to our understanding of ice sheet dynamics under moving loads, which is relevant for engineering and environmental studies in cold regions. ... : 96 pages, 19 figures, 70 references ...
