Abstract：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.
