... the sensitivity of the various constants of this equation, which depends on the GSI value and the D factor. The results show that the Hoek-Brown constants are very sensitive to both the GSI and the D factor, so to determine them exactly is very important for the rock engineering design. The sensitivity...

... of about ± 15 %, for rocks with GSI values up to 65. FOS values determined using Limit Equilibrium Method are mostly in higher (up to 10 %) side. If local approach is considered as more ‘correct’, depending on the parameters, results of the global approach can lie on the safe or unsafe site. Evaluation...

... formation was attributed a GSI value of 40 based on some geotechnical elements obtained from the field. This geomechanical classification has proved to be a useful link between in situ geological conditions and mechanical behavior. There are several excavations along the itinerary from which a single one...
