中文摘要：

为了保证露天矿边坡的稳定性，提高开采的安全性，减少人身财产损失，针对边坡稳定性存在的模糊不确定性和层次性的特点，采用模糊数学方法，建立边坡稳定性模糊综合评价模型。通过实地走访结合文献总结，选用5个影响因素及其对应的18个影响因子，集成误差传递原理、相似性和差异性分析以及区间数矩阵相对优势度分析建立动态权重。研究结果表明：该模型得到的结果能较准确地反映边坡的稳定程度，评价结果与实际结果相吻合，为边坡稳定性评价提供了一种可行的方法。

英文摘要：

In order to guarantee the slope stability of open-pit and improve the production safety and reduce the direct loss, considering the gradation and the fuzzy characteristics of slope stability, a fuzzy mathematical method was used and a model for fuzzy comprehensive evaluation of analysis of slope stability was established.Choosing 5 factors and 18 genes based on interview and summary of references.The dynamic weight was established by integrating error propagation,analysis of similarity and difference with the analytical method of relative superiority of the interval number matrix.The results show that the conclusion obtained by the model can reflect the practical situation of the slope stability.The evaluation and analysis results match with the practice.The model can be used as a practical approach for analysis of slope stability.
