In situ rock mass modulus is one of the most important parameters for designing the underground excavations. Rock Mass modulus can be determined by rock massclassification, equivalent media approach or by performing of in-situ tests. Ramamurthyequation has been applied to the numerical code, Flac, to evaluate rock mass modulussurrounding Masjed Soleyman Power House Cavern. The results have been compared to those obtained from back analysis and equations based on rock mass classification. This comparison indicates that the rock mass modulus obtained from Ramamurthyequations is more reliable than those obtained from equations based on rock massclassification. Another advantage of the Ramamurthy equivalent media is the possibility of distinguishing the variations of modulus due to the excavating. It is suggested that by helping of a numerical code and Ramamurthy equivalent media the variation of moduluscan be observed during different stages of excavation.
