Carrying capacities of the ice cover with surface reinforcement

Abstract: Practical experience shows, that mechanical properties of the ice cover are unreliable and can depend on various external factors if it is reinforced by traditional methods. For this reason, there is a need to develop alternative methods to increase the bearing capacity of ice, for example, the introduction of reinforcing elements into ice. The aim of the study was to compare the results of experimental and numerical research of the maximum deflections and bearing capacity of reinforced ice samples. Model experiments were carried out with ice reinforced with A400 steel on a specially assembled installation simulating pure bending conditions. When carrying out numerical experiments, the samples were reinforced with surface reinforcing frames with different physical-mechanical properties. The results of the stress-strain state of the ice cover are presented in the ANSYS program complex on the basis of the finite element method taking into account the physically nonlinear deformation model. The paper gives a qualitative and quantitative assessment of the effectiveness of the use of various composite materials, such as reinforcing elements. It is shown that the use of reinforcing materials to strengthen the ice cover significantly increases its bearing capacity.
Keywords: surface reinforcement, composite material, ice beam, model experiment, numerical research.
