Abstract

In this paper, the history of the rock mass classifications is discussed generally. Since the development of Terzaghi’s Rock-Load Classification System, several scholars have introduced quite different classification systems, which are briefly described. Most recent modifications of the Q system was done by Palmstrom, (1995). Unal, (1990) modified the RMR for weak rock. The detailed modifications are explained in this article, which includes the development of RMI and modified RMR. Importance of, site investigation and rock types have been evaluated for applying any of the classifications for design purposes. In the conclusion, advantages and disadvantages of the rock mass classification systems are discussed.
