摘　　要：根据某水电站地下厂房各勘探平硐现场统计的基础数据,采用RMR分类、Q系统法、水电系统分类法(HC法)、BQ法对地下厂区围岩岩体质量进行了分析评价,然后综合4种方法的评价结果,得到了各硐段的综合岩体质量类别,使这4种分类法相互补充、相互验证,达到综合确定围岩类别的目的,以此作为围岩稳定性分类的基础。此外,还对不同方法所得的评价结果进行了相关性分析。The quality classification of rock mass surrounding underground powerhouse were analyzed according the basic geological reconnaissance datum of exploration tunnel of a hydroelectric station with RMR classification, Q system, criterion of geological reconnaissance of water resources and hydroelectric project shorted HC and national criterion of engineering rock mass classification shorted BQ system. Syn- thesizing the analysis results of the four method the integrated rock mass quality was obtained. The four methods are reciprocal and can be checked with each other. The synthetic classification can be used as the basis to determine the rank of surrounding rock. Furthermore, this paper gaves a correlation analysis to the analysis results of each of the four method.
