This study was performed for the segment lining, an underground structure. Rebar of existing segment is designed in the form of lattice, so the rebar is influenced by the stress of segment. The existing segment designed before the introduction of optimal design concept is evaluated as the over design up to the year of 2018. In this study, we performed the tests intending to evaluate the structural performance of segment with an external diameter of Ø3400 by transforming the shape of internal
