Abstract
This study focused on compression failure and spalling of concrete which can be considered as limit states of plain concrete tunnel linings, and proposed a numerical simulation method considering the compression softening of concrete which can express above mentioned phenomena. From the simulation analyses on the loading tests of 1/5 scaled railway tunnel concrete lining and the reproduction analyses on seismic damages of actual mountain tunnels, it was confirmed that the crack and the compression failure of plain concrete can be properly expressed, and the seismic damages of the tunnel are reasonably reproduced by the proposed method.
