中文摘要：
针对现有地下结构岩体质量模糊分类方法的局限性与不足,在考虑岩体质量分类影响因素的模糊性与层次性基础上,重点研究模糊矩阵加权运算的非线性特征及影响因素权向量与隶属度的区间性特征,通过引进非线性模糊矩阵合成算子、区间数学理论和区间数矩阵相对优势度分析方法,建立岩体质量分类的区间非线性模糊评判方法。该方法减少评判的主观性,更好地反映出不利因素对评判结果的影响,从而使岩体质量分类方法更趋合理化,并使其具有更强的可操作性。工程实例计算及其与同类方法进行比较分析均表明了该方法的可行性与合理性。
英文摘要：
Aiming at localization and deficiency of existed fuzzy classification methods for rock mass quality in underground structures,the nonlinear weighting operation of fuzzy matrix as well as the interval feature of the weight vector and membership of the factors for the rock mass classification are specially studied considering the properties of the fuzziness and grade of factors.Moreover,by using nonlinear fuzzy matrix composition operator and interval mathematical theory along with the analytical method of relative superiority of the interval number matrix,the interval nonlinear fuzzy judgment method for rock mass classification is established,which can reduce the judgment subjectivity and enhance the influences of the adverse factors on the judgment results.So the method makes the rock mass classification much more rational and easier to operate.The computation results of practical engineering and its comparison with those of other classification methods show that it is reliable and reasonable.
