( 2 ) the rock mass quality was assessed based on the data obtained from exploration adits with the methods of engineering geological classification for surrounding rock mass , bq , rmr and q - system successively . and th en the correlations between the assessment results of different methods were discussed 基于勘探平硐獲取的資料,運用“圍巖工程地質(zhì)分類法” 、 bq法、 rmr法和q系統(tǒng)法進行了地下廠區(qū)巖體質(zhì)量評價;討論了四種不同方法評價結(jié)果之間的相關(guān)性。
Standard for engineering classification of rock masses ( gb50218 - 94 ) , the rock engineering geological classification of code for water resources and hydropower engineering geological investigation ( gb50267 - 99 ) , rock mass rating system ( bieniawski , 1973 ) and q - system were used in the rock mass quality classification . a evaluate system relative to the rock mass mechanism of the left bank rock mass was achieved finally 采用工程巖體分級標準( gb50218 - 94 ) 、水利水電圍巖工程地質(zhì)分類( gb50267 - 99 ) 、巖體地質(zhì)力學rmr分類及巖體質(zhì)量指標q系統(tǒng)圍巖分類,對左岸地下洞室區(qū)圍巖按其基本指標作出定量化評分、分級。
