In any engineering classification system, the minimum rating is called “poor rock mass” and the maximum rating is called “excellent rock mass.” Thus, every parameter of a classification plays a more dominant role as overall rating decreases, and many classifications are accurate in both excellent and poor rock conditions.

Based on research, many classification approaches are scientific. Nevertheless, the scientific spirit of prediction, check, and cross-check should be kept alive.
chanics classification rock mass rating (RMR), or both. In de veloping their empirical failure criterion for intact and heavily jointed rock masses, Hoek and Brown turned to rock mass clas sification schemes for the prediction of rock mass strength.
The backgrounds of the two classifications used most frequently are. Short on the Q-system. The Q-system for rock mass classification, developed at the Norwegian Geotechnical Institute (NGI) inoriginally included a little more than tunnel case histories, mainly from Scandinavia (Barton et al., ).
In the system was updated to include more than cases (Grimstad and Barton, ).File Size: KB. Rock mass classification methods are commonly used at the preliminary design stages of a construction project when there is very little information. It forms the bases for design and estimation of the required amount and type of rock support and groundwater control measures.
Rock Mass Rating Bieniawski () published the details of a rock mass classification called the Geomechanics Classification or the Rock Mass Rating (RMR) system. Over the years, this system has been successively re- fined as more case records have been examined and the reader should be aware that Bieniawski has made significant changes in theFile Size: 2MB.

Rock Mass Classification The objectives of rock mass classifications are to: Identify the most important parameters influencing the rock mass. Divid k f f l hde a rock mass formation into groups of similar behaviour.
Provide a basis for understanding the characteristics of each rock mass class. Relate experiences of rock conditions at one site to those at another.

Based on estimation of six rock mass parameters, a Q-value for a rock mass can be calculated. This value gives a description of the rock mass quality.

Rock material is the term used to describe the intact rock between discontinuities; it might be represented by a hand specimen or piece of drill core examined in the laboratory.
The rock mass is the total in-situ medium containing bedding planes, Author: B. Brady, E. Brown. The rock mass is divided onto blocks or sheets, a few centimeters thick near the ground surface and becoming thicker with depth until it fades out completely at depth of about 50 m.

Introduction: Barton et al. () at the Norvegian Geotechnical Institute (NGI) proposed the Rock Mass Quality (Q) System of rock mass classification on the basis of about case histories of tunnels and caverns.
It is a quantitative classification system, and it is an engineering system enabling the design of tunnel supports. This selection process is based on the condition of the rock, which is difficult to determine quickly and accurately during tunnel excavation.
The present paper uses the excavation of two tunnels to demonstrate that it is possible to assign rock mass classifications accurately based on rock strength when boring a uniform rock by:
