摘　　要：水对路基路面结构的影响较大,对于城市交通,道路排水设施达不到要求是形成道路水害的主要原因当水渗入路面结构中时,易导致路面出现裂缝、车辙、冻胀等;水渗入路基结构后,会导致路基填料含水量增大,削弱路基的承载力,增加沉降量,造成道路断裂、塌陷等问题。因此,对高等级公路的路基路面排水要求越来越高。论文根据实际工作经验,对高等级公路路基路面排水设施进行系统的分析和研究,对提升公路施工质量提出了可行性的建议。Water has a great influence on roadbed and pavement structure.For urban traffic,road drainage facilities are not up to the requirements,which is the main cause of road water damage.When water penetrates into pavement structure,it is easy to cause pavement cracks,ruts,frost heave,etc..After the water infiltrates into the subgrade structure,it will lead to the increase of water content of subgrade filling,weaken the bearing capacity of subgrade,increase the settlement amount,and cause road fracture,collapse and other problems.Therefore,the roadbed and pavement drainage requirements of high-grade highway are higher and higher.According to the practical working experience,the paper systematically analyzes and studies the drainage facilities of subgrade and pavement of high grade highway,and puts forward feasible suggestions for improving highway construction quality.
