摘要
为了对露天矿边坡的稳定性进行综合评价,本着"先定性后定量,先整体后局部"的思想,将基于模糊数学思想的模糊综合评判方法与传统极限平衡理论结合起来,对露天矿边坡稳定性问题进行定性分析和定量评价,并将两种分析结果进行对比和相互验证,从而使分析结果更为合理。结果表明:两种评价方法的综合运用可以发挥二者的相互补充作用,对于评判结果中稳定性差的区域,利用极限平衡法进行定量计算,既能克服单独采用极限平衡法进行评价所产生的巨大计算量,又能弥补模糊数学方法的主观性,从而对露天矿边坡稳定性进行综合评价;同时现场实例分析结果也表明利用两种方法对边坡的综合评价结果与现场实际相符。
In order to evaluate the stability of slope synthetically, fuzzy mathematics, and ultimate equation methods are combined according to the principle of ＂From qualitative analysis to quantitative analysis and from whole to part＂. So the stability of open pit slope can be analyzed through qualitative analysis and quantitative analysis, then two analytic results are conpared and validated each other. Accordingly, the slope stability is evaluated synthetically and the analysis result is more reasonable. As a result, the comprehensive application of two methods can reinforce each other, for the weak areas, the ultimate equation methods are used, therefore, the enormous workload of ultimate equation method and subjectivity of fuzzy mathematics are avoided. At the same time, the analysis of the example indicates the evaluation result conform to the practice of open-pit mine.
