Study of the influence of surface reinforcement on the bearing capacity of ice

Practical experience shows that the physical and mechanical properties of the ice cover are unreliable and can strongly depend on various external factors (the presence of snow and wind at the time of freezing, the ambient temperature), if it is reinforced by traditional methods. In this connection, the problem of increasing the bearing capacity of ice by alternative methods, e.g. by introducing reinforcing elements into the ice, is an urgent problem today. The aim of this work is to determine the effect of various reinforcing materials on the carrying capacity of the ice cover. First, a comparison was made between the results of experimental and numerical studies obtained for the maximum deflections and the carrying capacity of ice samples strengthened with steel reinforcement according to the proposed scheme. Secondly, numerical investigation of the strength of ice upon reinforcement with various composite materials was performed. Experiments on strengthening ice samples with A400 steel reinforcement were carried out on a setup specially designed for simulating pure bending conditions...
