对广东省某高速公路进行路况调查后,根据调查结果,研究预防性养护对策选择流程、养护路段划分指标和方法。采用车辙深度、横向裂缝长度和路面抗滑性能指数三指标,使用动态聚类法,划分预防性养护路段。得到了预防性养护对策选择的流程,给出了聚类分析法划分路段的过程和结果。结果表明,采用该流程进行养护措施的选择,科学性、客观性强;聚类分析法用于高速公路养护路段的划分可取得良好的效果。
After a highway survey of a highway in Guangdong Province, according to the survey results, we study the selection process of preventive maintenance measures and the indicators and methods for the conservation of road sections. Using rutting depth, transverse crack length and pavement slipperformance index three indicators, the use of dynamic clustering method, the division of preventive maintenance section. The process of selecting precautionary conservation measures is given, and the process and result of cluster analysis are given. The results show that the selection of conservation measures using this process is scientific and objectivity. Cluster analysis can be used to divide the section of expressway maintenance and obtain good results.
