Both of conventional tunnelling and shield tunnelling methods can be applied to Diluvial and Neogene deposits, on which megacities are located in Japan. Since the lining design methods for both tunnelling methods are very different, a unified concept for tunnel lining design is expected. Therefore, a frame structure analysis model for tunnel lining design using the ground reaction curve had been developed, which can take into account the earth pressure due to excavated surface displacement to active state including the effect of ground self-stabilization, and the excavated surface displacement before lining installation. In this paper, to discuss its performance, the measured earth pressure acting on the lining at the site in Diluvial deposit was compared with the calculated one by the developed model and the conventional model. As a result, it was confirmed that the developed model can represent the earth pressure acting on the lining reasonably.
