Recently, Seismic design criteria for major domestic structures has been being improved constantly, because the importance of seismic design for major public infrastructures is largely recognized. A preliminary assessment of the seismic performance on the existing railway tunnel, a precedent task before conducting a detailed assessment, can be use as the standard of judgement to decide whether to perform a detailed assessment or not. On the other hand, There are no reasonable study in this area. In this study, an assessment method was presented to evaluate a seismic performance of the existing railway tunnels which seismic design are not performed more economically and rationally.
