The number of existing subway structures in metropolitan areas that have been in service for 50 years is increasing. In addition, design methods for structures constructed in different periods of time have been rationalized and applied to load systems, structural models, etc. as appropriate. In this paper, the effects of the structural model and the calculation formulas for lateral soil pressure on the cross-sectional verification of members were investigated for shallow and deep excavation. As a result, it was confirmed that the difference in the structural model had a significant effect on the bending moment. It was also confirmed that the different calculation formulas for lateral soil pressure have a significant effect.
