摘要
围岩稳定性评价是一个复杂的不确定性问题,运用集对分析方法刻画围岩稳定性评价的确定与不确定性,构造了基于三角模糊数的差异度系数,建立了围岩稳定性评价的集对分析与三角模糊数综合评价模型。将该模型运用于实际工程并与投影寻踪插值法、可拓方法及模糊识别法等评价方法的评价结果进行了比较,结果表明运用集对分析与三角模糊数综合评价模型对围岩稳定性评价是可行的。
Evaluation of the stability of surrounding rocks is an intricate and uncertain question. Certainty and uncertainty of evaluation of the surrounding rock stability are depicted by Set Pair Analysis and coefficient of varia bility is described by Triangular Fuzzy Number to develop the variability coefficient based on Triangular Fuzzy Number, building a model of overall evaluation of the set pair analysis and the Triangular Fuzzy Number in the assessment of surrounding rocks. The model is applied in the actual engineering projects and compared with the projection tracking interpolation, extension method, fuzzy diagnosis and other evaluation method. The results show that it is viable to use the Set Pair Analysis and the model of overall evaluation of Triangular Fuzzy Number in the assessment of stability of sur rounding rocks.
