The study was conducted on the basis of finite element modeling in the PLAXIS 2D software package, taking into account the stages of construction and the interaction of the structure with the soil mass.<\/p>\n<p style=\"text-align: justify;\">Three calculation schemes are considered: monolithic, multi-hinged and elastoplastic. A comparative analysis of the internal forces, stresses, and displacements of the structure at depths of 52, 62, and 72 m was performed. The results were evaluated in absolute and relative terms, as well as in the form of dependency graphs.<\/p>\n<p style=\"text-align: justify;\">It is proved that in terms of indicators characterizing the global deformability of the structure, the differences between monolithic and multi-hinged schemes are insignificant, which makes it possible to consider the monolithic scheme as an acceptable engineering approximation for calculations on the deformability of the structure and forecasting the movement of structures in the ground. At the same time, the results of the calculation of internal forces demonstrate a high sensitivity to the joint model, especially with increasing depth of laying. It is revealed that taking into account the ductility of joints in the form of elastoplastic bonds mainly affects local forces with limited impact on the overall deformability of the system. New data has been obtained on the difference in the influence of the model of lining joints on the calculations of the stress-deformed state with a change in the depth of laying of single-vaulted stations.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> single-vault station; deep laying; connection models; stress-strain state; finite element modeling; PLAXIS; ground \u2014 structure interaction; internal forces; deformability<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mursalimov Timur Ildarovich Russian University of Transport (MIIT), Moscow, Russia E-mail: mursalimov_t.i@list.ru RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=1313999 Sonin Aleksandr Nikolaevich Russian University of Transport (MIIT), Moscow, Russia E-mail: axsonin@yandex.ru RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=1057345 Abstract.
