摘要: 在利用测线法对地表节理调查统计的基础上,提出了基于JSR (jointing structure rating)指标的地表岩体质量评价方法.以高放废物地质处置北山预选区地表岩体为研究对象,利用JSR指标对芨芨槽、算井子和新场地段地表岩体进行节理发育程度和地表岩体质量评价.结果表明:芨芨槽地段地表岩体比算井子地段节理发育程度低,地表岩体质量等级高,从而为高放废物地质处置场址比选提供依据.同时研究了JSR指标与传统Q指标的定量关系,并修正了JSR指标的分级范围.

关键词: 岩体质量, 高放废物处置, 节理调查, JSR, 节理发育程度

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
