A tunnel is an underground structure constructed through the neighboring rock or soil mass. Typically, the length of a tunnel is considerably greater than its width. In order to withstand the pressures exerted by the earth in all directions, tunnels are constructed. This review article provides an exhaustive examination of tunnel structures, including a discussion of their numerous applications, design philosophies, and construction methods. The primary objective of this research is to evaluate the structural characteristics of tunnel lining structures subjected to static loading conditions, employing Finite Element Analysis (FEA) through the ANSYS simulation package. The methodology involves CAD design, error checks, discretization using hexahedral elements, and simulation with applied static loads and boundary conditions. The obtained FEA results encompass deformation, normal stress, and shear stress, revealing commendable resistance and stability in the tunnel lining structure. This research, marked by its utilization of advanced simulation techniques, signifies a crucial stride in understanding and enhancing the reliability of tunnel structures for future infrastructure projects.
