Rock mass classification in rock engineering is an essential stabile analysis based on engineering geology analogue. As national standard of China, BQ qualification is ubiquitous for all kinds of engineering rock. However, rock mass with intercalated bed is mechanically unique, so it is reasonable to modify Formula BQ in order to match its feature. Taking underground cavities of a large hydropower station in Southwest China for example, rock mass structure and quality evaluation were studied. The result agrees basically with the one acquired by RMR System.
