Abstract:
For engineering analysis and design of structures in rock mass, rock mass classification systems often serve as a main tool. Due to the difficulties in retrieving relevant strength parameters of rock mass, classification systems are frequently applied to serve many applications like in assessing Deformation Modulus, Poisson ratio etc. In this study, the authors used four different rock mass classification systems for Diamer Basha Dam and Kohala Hydropower Project sites in order to obtain numerical values which are indicators of qualities of the rock mass. Both sites have different rock characteristics. Diamer Basha Dam Site consists of strong intrusive igneous rocks while Kohala Hydropower Project Site has weak sedimentary rocks. The classification systems used are Rock Mass Rating, Rock Quality Index, Rock Structure Rating, and Geological Strength Index. New correlations have been suggested among these systems after comparing with some existing correlations.
