摘　　要：依托于锦屏I级水电工程,以实测资料为基础,系统地运用参照对比方法、数理统计分析方法和相关关系推导方法,对岩体块度指数的量化取值进行分析研究,确立整体状、块状、次块状、镶嵌、碎裂结构岩体块度指数分级临界值。它们与以往的工程相比,既具有共同性,也存在一定的差异性。因此,锦屏岩体块度指数的量化取值研究成果丰富了该领域的研究内容。所利用的研究方法,对岩体结构其他指标的确定具有借鉴意义。Supported by project of Jinping I hydropower station,based on field measurement data,quantitative analysis of rock mass block index was performed with systematic synthetical methods including contrast analysis,statistical analysis and deduction of relativity.As a result,the critical values of rock mass block index were established for integrated rock mass,block rock mass,subblock rock mass,mosaic rock mass and cataclastic rock mass.Compared with the same index of early geological engineering,they showed consistency as well as difference.The research findings enriched the study content in this field.These methods used to get quantitative rock mass block index are potential reference for the establishment of other criteria.
