应用聚类分析法确定沥青路面预防性养护方案的研究

针对以经验法制定预防性养护方案的缺陷，宜采用可量化的方法设计预防性养护方案。在深入调查预防性养护技术发展历史和研究现状的基础上，根据多年来广东省成功运用预防性养护技术的经验，提出了预防性养护方案的设计流程。将系统聚类法和动态聚类法引入该流程，给出了聚类分析法划分养护路段的具体步骤。依托实际工程项目，于2006年10月选取广东省某高速公路进行验证，设计了该高速公路2007年的养护方案，并于2007年5月得到了实施。结果表明，该流程适用于设计预防性养护方案，聚类分析法是设计预防性养护方案的有效手段。

Studying the cluster analysis of the Preventive Maintenance Program for Flexible Pavement

To remedy the defects of making a preventive maintenance program by way of experience method, the designing procedure of the preventive maintenance program is proposed on a basis of thorough investigation of both the developing history and researching status quo of preventive maintenance technology, and also on a basis of enriched experience in Guangdong Province for many years. The methods of hierarchical cluster and dynamic cluster being introduced to this procedure, specific steps of dividing segments are provided. Adopting this procedure to design the preventive maintenance program of an expressway for the year 2007 in Guangdong Province, rational outcome has been generated. The outcome manifests that the procedure is suitable for designing the preventive maintenance program. Besides, cluster analysis is an effective means of designing a preventive maintenance program.
