| 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。

| Abstract: | Based on the indeterminacy of surrounding rock quality, the fuzzy mathematical method is established for evaluating the stability of surrounding rock.Six indirect factors on rock quality are chosen to test in laboratory. Fuzzy comprehensive evaluation have been found after processing those indirect factors by principal component analysis based on maximum membership principl and the evaluation model for rock quality has been got. . The quality of rock is evaluated by the model base on principal component analysis, and the quality sort of six factors of diferent rocks is given. It is shown that the evaluation results by the model and the actual quality of rock samples are well coherent. |

| Keywords: | surrounding rock quality fuzzy comprehensive evaluation maximum membership principle evaluation model |
