回采巷道围岩分类的模糊聚类分析方法

Fuzzy clustering analysis of tunnel surrounding rock classification

影响回采巷道围岩稳定性的因素有众多,各影响因素对围岩稳定性的影响程度也不一样,而回采巷道的分类标准及分类指标的确定却具有一定的模糊性,因此,采用模糊聚类分析的方法,建立模糊聚类分析的模型,对我国回采巷道进行分类,这将更加符合实际情况。本文对比运用模糊等价聚类分析法和模糊ISODATA聚类分析法对我国部分巷道进行了分类计算。

There are many factors influencing instability of surrounding rock, and the degree of influence of each factor is different. Decision of classification standards and indexes of gateway has fuzzy aspect, therefore, it is closer to the reality to apply the method of fuzzy clustering analysis to establishment of its analysis model and classification of gateway. The paper makes a calculation of classification to partial gateway by using the method of Fuzzy equivalent clustering analysis and Fuzzy ISODATA clustering analysis.
