摘 要: 选取岩体饱和抗压强度、岩体质量指标、体积节理系数、岩石内纵波波速值、嵌合程度和完整性系数作为岩体质量分级的指标因素，从系统角度入手，在一维云的基础上提出一种模糊RES(岩石系统工程)-多维云岩体质量的分级模型。结果表明：以云模型改进RES编码方式，可以有效弱化RES的主观性；基于改进的模糊RES分析了因素-因素、因素-系统间交互的作用，从系统的角度确定了因素的重要度；结合每个指标因素以多维云理论生成5朵六维岩体质量等级云模型，以软件程序实现工程实例验证，与实际地质报告、可拓法、一维云模型法评判的结果一致。

Abstract:The saturated uniaxial compressive strength, rock quality designation, acoustic longitudinal wave velocity, chimerity and integrality coefficient are selected as the index factors of rock mass quality classification. Based on the system engineering and one-dimensional cloud theory, a fuzzy RES (Rock engineering system)—multidimensional cloud model for rock mass quality evaluation was proposed. The results show that improving the RES coding mode with cloud model can effectively weaken the subjectivity of RES. Based on the improved fuzzy RES, the factors-factors and factors-system interactions are analyzed, and the degree of importance of factors are determined from the perspective of the system. According to each index factor, five six-dimensional cloud models of rock mass quality grade are generated by multidimensional cloud theory. The method is compiled by the software program and verified by an engineering example. The result highly agrees with the geological report, extension theory and one-dimensional cloud model theory.
