Abstract

In this research, the classification and characterization of rock masses did not use Rock Mass Rating (RMR), because some parameters of the RMR such asjoint spaces, joint conditions namely, apertures, persistence, joint fillings could not be determined during the study, so rock mass classified could be determined by compressive strength using the pocket penetrometer. Tunnel stability in very weak rock was analyzed using numerical modeling, the numerical modeling method used was the finite element method with RS 2019 software (Rocscience). Tunnel stability was assessed bytunnel displacement, strength factors, and probability of failure based on support capacity.
