摘要
在模糊物元分析的基础上,结合欧氏贴近度的概念,应用基于欧氏贴近度的模糊物元分析方法对岩土边坡稳定性进行综合评价.将各滑坡的稳定性作为物元的事物,以它们的各项评价指标及其相应的模糊量值构造复合模糊物元,通过计算与标准模糊物元之间的欧氏贴近度,并采用层次分析法计算各评价指标的权重,实现对岩土边坡稳定性的综合评价与排序.通过对实际边坡稳定性的分析,取得了较好的效果.
In order to evaluate stability of geotechnical slope, the paper applies a new method on the basis of the fuzzy matter-element analysis and combined with the concept of Euclid approach degree, regarding the stabilities of each slope as the object of matter-element and constructs the compound fuzzy matter-element with the evaluation factors and their fuzzy value of the object. Through calculating Euclid approach degree between the fuzzy matter-element and the standard (the best) fuzzy matter-element, the paper achieves on comprehensive evaluation on geotechnical slope stabilities and its optimum order, with the calculation of weight adopting the analytical hierarchy process method. The model is applied to the evaluation of geotechnical slope stability and good effect has been achieved.
