| dc.description.abstract | ENG: The paper analyses the structure of a metro vestibule and considers the possibility of impact loading affecting it. Three-dimensional finite element models were developed to research changes in the stress-strain state of the metro vestibule. The models reflect the complex structure of the vestibule, including the excavation support as a “slurry wall” and the depth of the structural arrangement. The developed models simulate three depths of the structural arrangement (1.8 m; 3.6 m; 7.2 m). A numerical analysis of the models was performed to estimate the impact loading applied as a quasi-static effect. The patterns of changes in the stress-strain state of the metro vestibule, considering the depth of the structural arrangement, were obtained. A reinforced-concrete slab is proposed as the reinforcement structure for the vestibule. A numerical analysis of the reinforcement structure for impact loading was performed. | en |
