| 摘 要： | 针对边坡稳定性影响因素的复杂性、随机性和模糊性的特点,建立了基于可变模糊识别边坡稳定性评价模型。首先应用主观权重对客观权重进行修正得到模型的动态权重,然后确定评价单元指标的级别特征值及指标最优隶属度,最终得到各评价样本的边坡稳定性等级。通过工程实例验证了该评价方法的可行性。

| Abstract: | Aiming at the complexity，randomness and fuzziness of the impacting factors for slope stability，a variable fuzzy recognition-based slope stability evaluation model is established. Firstly，the dynamic weight of model is obtained through revising the objective weights with the subjective weights; and then，the index level eigenvalues and the index optimal membership degrees of the evaluation units are determined; finally，the levels of the slope stability degree of all the evaluation samples are obtained. The feasibility of the evaluation method is demonstrated through an actual engineering case. |
