摘　　要：针对隧道围岩分级问题的复杂性,基于集对分析理论,选取岩石单轴抗压强度Rc、岩体完整性指数Kv、洞轴线与主要结构面的夹角θ、结构面状况Ss和地下水流量W 5个因子建立隧道围岩分级的评价指标体系,将围岩分级的各个评价指标与评价标准构筑成一个集对,建立隧道围岩分级的集对分析模型,并引用围岩实测样本数据进行模型检验,运用集对分析法以实际的围岩为例进行级别判别.研究表明:集对分析法判断结果与实际围岩级别相符,由此证明该方法用于隧道围岩判别是可行的,具有较高的准确度.集对分析法原理简单、算法简捷、可操作性强,可作为一种有效的围岩分级方法.Considering the complexity of surrounding rock classification,some factors such as rock uniaxial compressive strengthen,integrality coefficient of rock mass,the angle between tunnel axis and the main joint,joints condition and seepage measurement of groundwater are selected as evaluation indexes.The evaluation indexes and the standard for surrounding rock classification are used to constitute a set pair.A model of tunnel surrounding rock classification based on set pair analysis is established,which is tested by measured samples of surrounding rock.The model is applied to actual tunnel.The research concludes that the results of SPA are in good agreement with practical situation of surrounding rock.Also,the method of set pair analysis applied to the classification of surrounding rock is feasible and has high accuracy.SPA is simple and has strong maneuverability,which is a good method for surrounding rock classification.
