摘　　要：采用Q系统、RMR和BQ三种岩体质量分级方法对西南某水电站左岸坝基部分岩体进行了分级,然后对三种方法进行相关分析,认为分级结果具有良好的相关性。在充分调查和资料分析的基础上,对岩体工程地质分级在实际工程中的应用提出了具体指标和实际的操作方法。Three methods, Q system, RMR and BQ, are adopted to classify the left bank dam foundation rock mass quality of a hydropower project and the correlation among these methods is also analyzed in this paper. The analysis shows that the results have good correlation. The paper has put forward both specific indications and practicabIe method of operation for application of the rock mass quality classification to practical construction projects based on the plenty survey and data analysis.
