摘　　要：岩体稳定性的正确分类是确保隧道工程和地下洞室合理设计及安全运行的重要环节,应用信息熵理论和可变模糊集合理论,探讨了岩体稳定性的熵可变模糊分类模型,以及基于岩体稳定性分类指标信息熵和专家经验知识的综合权重确定方法,并应用于实际工程,以及同其他分类方法进行了对比分析,结果表明该法是有效可行的,且更客观。To ensure the rational design and safe operation of tunnel engineering and underground engineering projects, the exact classification of rock mass stability is of prime importance. Based on the information entropy theory and the variable fuzzy sets theory, a new entropy variable fuzzy classification model using a relative difference function is discussed in this paper. And a method for determining comprehensive weights of evaluation factors based on the information entropy weights and the expert experience weights is also investigated. The results of a practical example are compared with those by other methods, which shows that the proposed method is feasible, effective and more objective.
