摘　　要：为了评价岩石的稳定性,基于岩石质量影响因素的不确定性,应用模糊数学方法,选取了能够间接反映岩石质量的6项主要指标,构建了影响岩石质量的指标体系。根据最大隶属度原则,采用模糊综合评价原理对6项指标进行评价和处理,得出了岩石质量的数学评价模型。在分别对不同部位的岩石样品的6项指标进行室内测试得到相关数据后,运用该模型对不同部位的岩石样品进行了评价,将结果与工程实际情况进行对比,结果表明,该模型的评价结果与矿区实际情况基本一致。证明了岩石质量模糊综合评价模型的科学性和可行性。In order to evaluate the stability of the rock,based on the uncertainties of the influence factors of the rock quality,six main indexes which can indirectly reflect the rock quality were selected by fuzzy mathematics method,and the index system which can affect rock quality was constructed.According to the principle of maximum membership degree,the fuzzy comprehensive evaluation principle is used to evaluate and deal with the six indexes,and the mathematical evaluation model of rock quality is obtained.After the relevant data were gained from the six indexes of rock samples in different parts based on the indoor test result,the model was used to evaluate the rock samples of different parts.The results were compared with the actual situation of the project.The results showed that the evaluation results of the model and the actual situation of the mining area is basically the same.It is proved that the fuzzy comprehensive evaluation model of rock quality is scientific and feasible.
