摘要
在岩体的力学和水力学分析中,岩体结构面产状的分析是极为重要的基础工作。传统的结构面产状图形分析较粗糙,因此模糊聚类方法得到了一定的应用。分析了模糊等价聚类方法和模糊软划分聚类方法在岩体结构面产状分析中的优缺点,并将上述2种方法结合起来形成岩体结构面产状的综合模糊聚类分析方法,给出具体的计算方法和过程。实例分析表明,结构面产状综合模糊聚类分析方法对结构面产状的分类合理,结果可靠,可根据实际问题灵活运用。
The analysis of joints occurrence in rock mass is an important basic work for mechanical and hydrodynamical behaviors analysis of rock mass. Traditional analysis of plots methods is inadequate to this work; therefore a fuzzy clustering analysis is developed. Both the advantages and disadvantages of fuzzy clustering method and ISODATA fuzzy clustering method are analyzed; then the two fuzzy clustering methods are combinated into a synthetical fuzzy clustering method; and a procedure of the synthetical fuzzy clustering method is proposed. A case study shows that the results of the synthetical fuzzy clustering method are reasonable and reliable.
