The aim of this work is to study the effect of the transverse static load shape on the stress-strain state of the ice cover. The construction of many hydraulic structures, offshore pipeline laying, and some types of track arrangements, in particular, blasting operations, are often associated with the use of the bearing capacity of the ice cover of rivers and reservoirs. Such works are being widely developed due to their significant productivity and economic efficiency in practice. Obviously, the use of ice cover requires special calculations to determine the safe load-carrying capacity for various loading conditions. In addition, river ice is often used for ferries and construction sites in various types of work. The available methods for determining the bearing capacity of the ice cover, based on theoretical developments and experimental studies in laboratory and field conditions, allow the use of the theory of elasticity under certain loading conditions. In these cases, the ice cover is considered as an isotropic elastic medium on the elastic foundation. Such an approach is approved by the reviewed experimental and theoretical studies as an expedient to study the effect of the transverse load shape on bending stresses in the ice cover. In the framework of the formulated problem, the effect of the load shape on the stress-strain state of the ice cover is assessed considering the impact of the aspect ratio of the sides of the transverse static uniformly distributed over the rectangle area loading, which is constant in the total value, on the behavior of an infinite isotropic elastic ice plate arranged on elastic Winkler-type foundations. The calculations are performed for the same loads distributed over the circle and square areas. As a result, the most appropriate load shapes are determined.
