DISCUSSION ON THE INTERRELATION OF VARIOUS ROCK MASS QUALITY CLASSIFICATION SYSTEMS AT HOME AND ABROAD
各类岩体质量评价方法的相关性探讨

A large number of rock mass quality classification systems have been put forward in the world. Recent advances in this field at home and abroad are reviewed systemically in this paper. The relationship between rock mass structure, rock mass quality and its classification is summarized. Finally,a relation of interrelation,comparison and conversion among the main rock mass quality classification systems are proposed.
