摘要
用岩石质量指标和岩体块度指数的理论,对钻孔岩心实测资料进行分析和对比研究,对钻孔周围岩体进行分级。结果表明:岩体块度指数在岩石质量评价中能更准确地反映其优越性,具有更为显著的工程意义。
Basing upon the theory of rock quality data(RQD) and rock block index(RBI),we attempt to have a correlation study on this theory and the classification of rock body around the drilling hole according to the measured data of a drilling hole rock core of Baoshan in Yunnan.The study result shows that the RBI can more accurately indicate the advantage in the assessment of rock quality,which has more evident engineering significance.
