摘　　要：为了克服传统围岩分类方法主观因素强、分类参数不全等缺陷,根据灰色关联分析原理,将确定的地下洞室围岩分类标准指标值设为被比较数列,将待分类围岩指标值设为参考数列,并采用层次分析法确定各分类指标的权重值,利用改进的灰色关联度计算方法确定围岩类别,构建了地下洞室围岩分类的新模型———基于层次分析法的灰色关联模型(GAM)。实例应用表明,GAM克服了传统围岩分类方法的不足,能较好地反映洞室围岩的质量等级,具有重要的推广意义。In order to overcome the drawbacks of traditional rock classification methods such as strong subjective fac tors and incomplete classification parameters, according to the principle of gray correlation analysis, the compared se- quence was composed of the indices of the classification standards for the surrounding rock in underground chamber, and the reference sequence was composed of the indices of the surrounding rock to be classified. And then the analytic hierar- chy process was used to calculate weight value of the indices of classification. Finally, the improved calculation method of gray correlation was applied to determine the surrounding rock classification. So, the model of gray correlation method based on analytic hierarchy process （GAM）, a new model of surrounding rock quality evaluation of underground cham- ber, was achieved. Application of an example shows that GAM can reduce the defects of traditional method and reflect the quality classification of the surrounding rock more accurately, which has important extended significance.
