针对现有岩溶区公路路基稳定性模糊评判方法的局限性与不足,在考虑岩溶路基稳定性主要影响因素的模糊性与层次性基础上,建立岩溶路基稳定性二级模糊综合评判模型,并通过重点探讨影响因素隶属度与权向量的区间性以及模糊矩阵加权运算的非线性特征,引入非线性模糊矩阵合成算子、区间数学理论和区间数向量矩阵的相对优势度分析方法,建立了岩溶区公路路基稳定性的区间模糊评判分析方法,该方法减少了评判的主观性,更好地反映了不利因素对评判结果的影响,从而使公路岩溶路基稳定性评判方法更趋合理化,且具有更强的可操作性。
Aiming at the limitations and deficiencies of the fuzzy evaluation method for the existing roadbed stability in karst areas, the fuzzy comprehensive evaluation model of karst subgrade stability is established based on the fuzziness and hierarchy of the main factors affecting the stability of karst roadbed. This paper focuses on the interval features of the influencing factors and weight vectors and the nonlinear characteristics of fuzzy matrix weighted operation. By introducing the nonlinear fuzzy matrix composition operator, the interval mathematical theory and the relative dominance analysis method of interval vector matrix, the karst area This method reduces the subjectivity of judgments and better reflects the impact of unfavorable factors on the judgments, so as to rationalize the method of judging the stability of highway karst roadbed, and has a stronger fuzzy evaluation method. The operability.
