As well known, a shield tunnel is one of typical long structures. Its lining has many segment joints in the cross section and in longitudinal direction. For rational design of a shield tunnel subject to strong earthquake motion or ground subsidence, it is essential to evaluate its longitudinal structural characteristics accurately. Namely, effects of the joints should be taken into account in structural calculation. This study shows approaches to evaluate the effects of the joints for longitudinal tunnel design. For this purpose, the authors present a numerical calculation model to predict longitudinal behavior of the shield tunnel. In this model, joint elements are introduced so as to evaluate segment joints.
