Improvement of the calculation of combined crossings

Abstract: In winter, ice crossings are opened in the north of the Far East region. Ice crossings remain the only way to connect such settlements with the mainland. The most reliable way to increase the bearing capacity for the passage of freight and passenger transport through water bodies is to freeze floating hinge bridges into the ice cover. At the time being, there is no methodology for calculating such crossings, so the purpose of the work is to improve the calculation of ice crossings, reinforced with metal pontoon structures from double-support hinged ferries. The calculation of these crossings, the graphs for calculating the permissible axial loads from the condition of strength and stiffness are proposed, and graphs for calculating the deflections of the ice cover under axial load are constructed. Deflections of the ice crossing with and without reinforcement were calculated. To confirm the selected design scheme, an experiment was carried out, which showed the correctness of the selected design scheme and the calculation method.

Keywords: ice crossing, deflection, axial load, design scheme, floating bridge, bearing capacity, two-bearing steam, hinge scheme
