摘　　要：为克服新建高速公路集料选择时重视某项指标而忽视整体性能的问题,避免集料分类评价过于主观而缺乏科学性,将模糊聚类分析应用于集料的分类选择.给出了模糊聚类分析方法的基本原理和计算步骤.选取甘肃某新建高速沿线9个碎石厂生产的粗集料,首先对粗集料的各项物理力学性能进行试验;然后将集料的9个技术性能指标作为原始数据,使用模糊聚类分析的方法对其进行标准化、建立模糊相似矩阵、计算传递闭包并聚类;最后利用F统计量加经验法检验分类结果的有效性和可靠性.结果表明:模糊聚类分析方法用于石灰岩粗集料分类是可行的,该方法可为道路建设初期集料的选择提供参考依据.To overcome the problem of paying attention to a certain index and neglecting the overall performance during selecting aggregates for a new highway,and to avoid the lack of scientificity due to too subjective classification evaluation of aggregates,the fuzzy cluster analysis was applied in the classification and selection of coarse aggregates.The basic principle and calculation steps of fuzzy clustering analysis method were given.Nine coarse aggregates produced by nine crushing plants along a new highway in Gansu were selected.The physical and mechanical properties of the course aggregate were tested.The fuzzy clustering analysis method was used to standardize with 9 technical properties of the course aggregates as original data,and the fuzzy similarity matrix was established to calculate the transitive closure for clustering.The effectiveness and reliability of the classification results were tested by F⁃statistic and experience method.The results show that the fuzzy clustering analysis method is applicable to the classification of coarse aggregate,and the method can provide reference for the selection of coarse aggregate before the highway road construction.
