| 摘 要： | 以路网内各组成路段的路面性能评价指标灰色关联分析结果为基础,借鉴灰色关联分析在模糊聚类理论中的应用方法,建立了路网路面使用性能评价模型.确定了灰色相似关系矩阵,并利用最大树法,得到了基于不同水平的聚类结果形成的谱系图,较为合理地反映了路网路面基本性能和状况分布.

| Abstract: | Based on gray correlative analysis of the pavement performance indexes of the component pavement units,the assessment model of network level pavement performance was established with the fuzzy clustering method.A fuzzy equivalence relational matrix was established.With the maximum tree method,a dendrogram was obtained on the basis of different clustering levels.As a result,the state of pavement performance can be described reasonably. |
