摘要：

针对以往地下工程岩体质量评判过程中存在的模糊性与随机性问题，根据岩石质量指标、岩石单轴饱和抗压强度、岩体完整性系数、结构面强度系数和地下渗水量这5项指标建立地下工程围岩稳定性评价指标体系.基于物元分析法，通过计算专家评判矩阵的效度物元及合成权重物元来确定评价指标的重要性.根据确定的评价标准，得到各评价因子隶属于各级别的综合云模型，并针对广州抽水蓄能电站二期地下工程岩体实测数据，先通过正向云发生器计算各评价因子所对应的各个评价级别的隶属度，再与其权重结合得到合成隶属度，然后以最大隶属度为依据判别出岩体稳定性所属级别.将该方法所得评价结果与约简概念格-模糊优选评判法、粗糙集-逼近理想解的排序法（RS-TOPSIS）进行对比，三者判别等级一致，表明该方法准确可靠，且免除了对大量样本的学习过程，能够克服评价指标定性语言和定量数值相互转换所产生的模糊随机性，可以用于地下工程岩体稳定性的评判.

Abstract:

Aiming at the problem of fuzziness and randomness existing in the process of the rock stability evaluation, five indexes including rock quality designation, uniaxial compressive strengthen, rock mass integrality coefficient, strengthen coefficient of structural plane and seepage measurement of groundwater were selected to be the underground engineering rock stability evaluation index system. Based on the matter-element analysis method, the significance of evaluation indicators was confirmed by calculating the validity matter-element of expert judgment matrix and the synthetic weight matter-element. The comprehensive cloud model of each evaluation factor belonging to each evaluation level had been generated based on the certain evaluation standard. According to the measured data of the second stage project in Guangzhou pump accumulator electricity station, the membership degrees of evaluation factors relative to the evaluation grades were calculated from positive cloud generator, and the comprehensive membership degree was determined by combining with the corresponding weight. Finally, the rock stability level was specified by the maximum membership principle. Comparing the evaluation results from the reduced concept lattice fuzzy optimum selection and the RS-TOPSIS method, it can be concluded that the method is accurate and reliable and can overcome the transformational fuzzy randomness between qualitative language and quantitative value, so it can be used to evaluate the rock stability in underground engineering.
Key words: matter-element analysis    cloud model    underground engineering    membership degree    surrounding rock stability evaluation
