摘要

针对边坡稳定性影响因素众多复杂，且存在模糊不确定性和层次性的特点，首先引入锚固边坡稳定性分析二级模糊综合评判模型，并基于模糊数学理论建立评价指标隶属度确定方法和模糊运算规则，从而建立出锚固边坡稳定性分析的二级模糊综合评判方法；然后，考虑评价指标重要程度取值的不确定性、专家判断的模糊性以及群组决策的优势，建立基于群组决策的不确定型层次分析（AHP）方法确定权重，进而建立出基于AHP的锚固边坡稳定模糊评判方法，最后通过工程实例分析和计算，表明文中方法的可行性与合理性。

Abstract

There are many complicated factors affecting slope stability. Considering the fuzziness and hierarchy feature of the factors

a secondary fuzzy comprehensive judgment model of stability of anchored slope is introduced. By using fuzzy mathematics theory to establish the method of determining membership degree and the operational rule of fuzzy

a secondary fuzzy comprehensive evaluation method is formulated. Taking account of the uncertainties of the importance degree of evaluation indices

the fuzziness of the judgment by experts and the advantage of group decision making

an uncertain analytic hierarchy process(AHP) based on group decision making is developed to calculating the weight vectors. Then fuzzy evaluation method of slope stability based on uncertain AHP is formulated. Finally

the method is used to analyze the practical engineering; it is shown that the method is feasible and reasonable.
