摘　　要：影响岩体质量的因素众多,岩体质量分级中往往面临因素考虑不全面、主观性强以及不同因素之间难以进行对比分析等问题,对准确性产生影响。物元可拓分析法的最大优势是可以对不同因素进行综合分析,从定性和定量角度对目标进行确定。针对某矿岩体质量评价工作,基于物元可拓分析法建立岩体质量评价体系,通过确定经典域、节域、待评物元以及权重,完成对岩体的质量评价。结果表明,利用该法对岩体质量的评价结果与工程岩体分级标准相近,证明了方法的合理性和准确性。同时,熵权法确定权重更加客观,物元可拓分析法降低了在分析中考虑不全面和专家主观性的影响。There are many factors affecting the quality of rock mass.In the classification of rock mass quality,there are some problems,such as incomplete consideration of factors,strong subjectivity and diffi-culty in comparative analysis between different factors,which affect the accuracy.The biggest advantage of the matter-element extension analysis method is that it can comprehensively analyze different factors and de-termine the target from the qualitative and quantitative perspectives.In view of the rock mass quality evalua-tion of a mine,the rock mass quality evaluation system is established based on the matter-element extension analysis method.By determining the classical domain,the nodal domain,the matter-element to be evaluat-ed and the weight,the quality evaluation of the rock mass is completed.The results show that the evaluation results of rock mass quality by this method are close to the engineering rock mass classification standard,which proves the rationality and accuracy of the method.At the same time,the entropy weight method is more objective to determine the weight,and the matter-element extension analysis method reduces the influ-ence of incomplete consideration and expert subjectivity in the analysis.
