摘　　要： 根据边坡稳定性评价指标具有多层次、多因素且计量与离散、定量与定性并存的特点,提出了采用可拓区间数的可拓层次分析法(EAHP)确定边坡稳定性评价指标权重的方法。该方法避免了传统层次分析法(AHP)的人为判断的模糊性和一致性检验的缺点;建立了边坡稳定性评价的指标体系、单因素法的评价等级标准和多因素综合法的评级等级分类及相应的支护方案;引入集对分析方法(SPA)建立了边坡稳定性评价的可拓层次-集对分析(EAHP-SPA)耦合模型。该模型在广昆高速公路路堑边坡得到了运用和验证,并与其他评价方法进行了对比分析,结果表明该模型物理概念清晰、方法简单、有效可行,能为边坡稳定性评价提供新的参考方法。 The extension hierarchy process（EAHP）method is proposed to determine the weight of slope stability evaluation whose evaluation indexes can be in multi-level,with multi-factors,with coesistance of measurement and discretization,and be qualitative and qualitative.Compared with AHP,EAHP can avoid the shortcoming of fuzziness of human judgment and consistency checking.An index system,single factor method for the grading criterion of slope stability,and multi-factor synthesis method for classification and support scheme of slope stability are established.The model of extension analytical hierarchy process and the set pair analysis（EAHP-SPA for short）are integrated as the model of evaluation.Compared with other methods,the evaluation coupling model has been applied to cutting slope of Guangzhou-Kunming Expressway.The analytical results confirm that the model is feasible and reasonable.
