Correlations between rock mass intactness index (Kv) and other rock mass classification indices ($ RMR_{89} $ system and GSI)
https://orcid.org/0000-0001-5296-9233
Abstract Rock mass integrity is related to rock mass quality and strength. It can be characterized by a single index, or a combination of multiple indices. In this paper, the rock mass integrity classification index and corresponding classification scheme are described. The relationship between intactness index and rock mass structure index in the $ RMR_{89} $ system is examined, and the relationship between Kv and Q′, representing the rock mass structure index in the Q system, was determined. Results of the case study show that there is a good correlation between Kv and the sum of the RQD ratings, joint spacing D, and the joint conditions in the $ RMR_{89} $ system. A better correlation exists between Kv and GSI|2013, a quantitative expression of GSI proposed by Hoek et al. (2013). Based on the above correlations, if a certain rock mass integrity index is unavailable in an engineering project, other indices can be used as alternative to complete the rock mass quality evaluation; however, because the data employed in this paper are from only two projects, the similarity of rock mass conditions should be thoroughly considered. More research is needed to supplement, validate, and revise the results of this study in the future.
