Abstract
RMR, Rock Mass Rating, is one of the famous rock classifications. However, RMR was proposed empirically and absolutely depends on the experience of engineer. Therefore, engineering verification is needed for RMR system itself. In this study, the factor analysis and the multiple regressions were performed in order to evaluate the validity of rating factor of RMR. Also numerical analysis was carried out using the FLAC based on Taguchi method, a kind of robust designs, in order to examine the support of tunnel corresponding to the revaluated RMR. As the result of the analysis new RMR was proposed with five minimized factors of intact rock strength, RQD, spacing, persistence and roughness of discontinuities.
