基于系统聚类的沥青路面车辙养护区域划分

摘要:

随着陕西省道路建设的高速发展,很多道路已经进入了养护期。而在陕西省道路病害中,车辙尤为严重。陕西省南北跨度大,气候环境差距明显,为了在养护决策时针对车辙病害采用不同的养护措施,本文调查陕西省10个地区的累年月平均最高气温,并将其换算为路表7.5cm处的温度。对此温度进行系统聚类,将陕西省的10个省划分为三个区域,可为车辙养护提供参考。

Abstract:

Many roads have entered the maintenance period. Among the road diseases, rutting is serious in Shaanxi Province. The north-south span of Shaanxi Province is large, the climatic environment gap is obvious. To adopt different maintenance measures for rutting disease in the maintenance decision-making, this paper investigated the cumulative annual and monthly average maximum temperature of 10 regions, converted it to the temperature at 7.5 cm of the road surface. This temperature is clustered, the Shaanxi Province are divided into three regions. This can provide reference for maintenance.
