Abstract

Based on the abundant field investigation and statistical data,the rock mass quality classification of the surrounding rock of the underground building in a hydropower station is carried out according to Rock Mass Rating(RMR) and Q System which are very popular in the world and classification system in the Hydroelectric Standard of P.R.C..Same results are obtained from these three kinds of classification systems and indicate that the rock mass quality is rather good.
