Abstract: Underground metro stations are influenced by critical external loads such as earth pressure, hydrostatic pressure, bedding spring stiffness and backfill soil cover. Optimization, constructability and sustainability is a need, which demands thorough critical analysis and design. The variation in design parameters like ground water level (GWT), bedding spring stiffness (ks) and earth pressure coefficient (ko) needs to be covered through the analysis. Accordingly, design demands the upper bound and lower bound parameters considerations for finite element analysis. This paper presents, best practices for finite element modelling approach such as mesh configuration, loading, geometry, support arrangement; analysis approach such as analysis parameters, solvers and design idealization of critical forces such as bending moment, shear force and axial force at wall slab junction and slab column junction based on the international codes such as Euro-code and Indian codes. Also paper compares the behavior of 2D and 3D finite element modelling of underground metro station.
