主 题:Ice beam Surface reinforcement Carrying capacity Numerical research Criterion of strength
摘 要:Ice crossings have been used for several ***,due to the active development of the Arctic shelf,supplies and minerals are provided and transferred on special transports on the surface of ice ***,ice crossings across rivers are used to reduce the length of transport *** methods of increasing the load bearing capacity of ice are ice freezing from above,ice freezing from below,and ice strengthening through a wooden copepod *** experience shows that the physical and mechanical properties of ice covers are unreliable and changeable in time and strongly depend on various external ***,ice covers should be strengthened through alternative ***,predicting the bearing capacity of ice crossings and exploring methods for their strengthening are *** this study,we consider the results of experimental and numerical studies on the bearing and deformation capacity of ice beams upon destruction from pure *** pure bending,ice breaks down in the ice crossing when transports move along *** were carried out with a specified reinforcement *** results of the model experiments were compared with numerical calculations in the ANSYS software *** on ice beams reinforced with various composite materials were also *** of samples in all cases occurred as a result of the formation of extensive cracks in the ice caused by the bending moment in the middle of the beam *** on the experimental and numerical research results,the use of a surface reinforcement in ice with various materials can increase the bearing capacity from 65%to 99%for this reinforcement scheme.
