The subsidence caused on the surface due to the construction of subsurface tunnels for various purposes in urban areas is a major concern for both the tunnel and the overlaid buildings. Seeing the importance of study, different models has been created keeping reference of commercial and residential buildings. The amount of surface deformation and the stresses so generated are calculated, which plays a paramount role before construction. These models are analyzed on circular and semicircular tunnels with various loading conditions and varying litho. In this paper, two software’s namely STAAD Pro and Rocscience were used for structural design and analysis respectively. The study gives the basic idea of behavior of these two shapes of tunnels with varying loading condition and strata which shows a path for predicting unforeseeable displacements in real life situations.
