基于灰色模糊聚类法的路网路面使用性能评价

Gray and Fuzzy Clustering Method-Based on Network Level Pavement Performance Assessment

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.

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.
