<p>The deflection and strain of the tunnel are essential issues for designing under gravity loading. For this reason, the present research proposes a novel technique to evaluate these responses of the tunnel easily. The nonlinear static analysis is performed to evaluate strain and deflection of the simplified form of the fixed-ended circular tunnel under uniformly distributed loading (i.e., super-structure plus sand). The range of verification results of this proposed concept is found to be (1.17 to 6.28) %, which may indicate a good accuracy of the validation. The deflection and strain show maximum values for the higher number of stories and tunnel lengths due to the increment of the self-weights of super-structure and tunnel. The ranges of variations of deflections and strains for variable tunnel lengths are found to be (2.4 to 30.3) % and (3.4 to 20.5) %, respectively, in the case of the 15-storied structure. So, these findings may help professional engineers in practice to evaluate the deflection and strain of the tunnel.</p>
