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 Applying to Network Level Pavement Performance Assessment

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:

The assessment model of Network level pavement performance was established by means of the fuzzy clustering method, which was based on gray correlative analysis among the pavement performance indexes of the component pavement units. The fuzzy equivalence relations were obtained. The maximum tree method was used, and the dendrogram was introduced on the basis of the different clustering level. Thus, the state of pavement performance can be demonstrated reasonably.
