Abstract: Based on the use of surveying method for surface joint investigation and statistics， a surface rock mass quality evaluation method based on the index-JSR was proposed. Taking the high-level radioactive waste disposal of Beishan preselected area as research object， the index-JSR was used to evaluate rock mass joint development degree and quality in the Jijicao section， Suanjingzi section and Xinchang section. The results showed that joints in the Jijicao section are less developed and the rock mass quality for Jijicao section is higher than that of Suanjingzi section. The results can provide site select basis for high-level radioactive waste geological disposal. At the same time， the quantitative relationship between JSR and Q was studied， and the scope of JSR index classification was corrected.

Key words: rock mass quality, high-level radioactive waste disposal, joint investigation, JSR, joint development degree
