【摘要】 地表岩体质量评价可为高放废物地质处置库初期选址阶段提供经济、客观的比选依据。不同的岩体质量评价方法由于侧重点不同,致使针对同一对象,评价结果会有一定的偏差。基于天湖候选场区钻孔周边花岗岩体的详细调查获得大量实测数据,采用BQ、Q和RMR等岩体质量分级方法,将不同分类方法之间分值区间的对应关系进行了"归一"化处理,再通过多方法的"综合平均"来评定研究区的岩体质量等级。评价结果证明研究区内西北部的岩体质量水平要高于东南部的岩体质量水平。更多还原

【Abstract】 The quality evaluation of surface rock masses can provide an economic and objective selection basis for the location of high-level radioactive waste geological repository. The evaluation results will be different for the same object, as the evaluation methods have different indicators. Through the detailed investigation of the granite rock mass surrounding the drilling area in the Tianhu candidate site, a large amount of measured data has been obtained. On the basis of rock quality grading methods such as BQ, Q, and RMR, the corresponding relationship between the score ranges of different classification methods was "normalized", and then a multi-method "comprehensive average" has been used to assess the quality of the rock mass in the study area. The evaluation results show that the rock mass quality in the northwestern of the study area is better than that in the southeast.更多还原
