围岩稳定性的模糊物元评价方法

在模糊物元分析原理的基础上，结合信息熵的概念，提出了基于熵权的模糊物元分析方法。在对围岩的稳定性进行综合评价时，把围岩的分类等级作为物元的事物，以它们的各项评价指标及其相应的模糊量值构造复合模糊物元，通过关联度计算，实现对围岩的综合评价。该模型被应用到黄河大柳树水电站导流洞围岩稳定性综合评价中，取得了较好的效果。

Fuzzy matter-element evaluation method for analysis of surrounding rock stability

Based on the principle of fuzzy matter-element analysis, the concept of information entropy is introduced to establish a fuzzy matter-element evaluation method. This method is utilized to comprehensively evaluate the stability of surrounding rock. The classifications of surrounding rock masses are regarded as the objects of matter-element and their indexes for evaluation as well as the corresponding fuzzy values are used to construct the composite fuzzy matter-elements. By calculating the relevancy the comprehensive evaluation of surrounding rock mass can be carried out. This model is applied to analyze the stability of surrounding rock in diversion tunnel of the Daliushu Hydro Project. The application shows that the model is effective and practical.
