摘　　要：模糊聚类分析方法是以模糊集为理论基础,针对监测对象间的模糊关系基于变形水平λ进行分类。本文将模糊聚类法应用到浙江省紧水摊拱坝变形水准网数据分析,首先计算相似系数rij建立模糊相似矩阵,其次采用平方法求取模糊等价矩阵,最后基于不同变形水平λ进行模糊动态聚类分析,获得监测对象稳定或变形的结果,达到变形分析的目的。Fuzzy Clustering analysis method is based on the theory of fuzzy sets and classifies the targets based on the level of deformation λ according to their fuzzy relationship.In this paper, the fuzzy clustering method is applied to data analysis of the deformed leveling network of Jinshuitan arch dam in Zhejiang province, Firstly, the similarity coefficient r ij is calculated to establish the Fuzzy Similarity Matrix, then the flat method is used to obtain the Fuzzy Equivalent Matrix.Finally, the fuzzy dynamic clustering analysis is performed based on the different deformation levels λ to obtain the results of the stability or deformation of the monitoring object and achieve the purpose of deformation analysis.
