为建立我国汽车路面谱数据库,需要路面不平度的相关信息。为此,在江苏省道路基本情况调查的基础之上,分析了影响路面平整度的因素,并选择公路技术等级、公路使用年份和路面铺装情况作为预测路面平整度的自变量。采用德尔菲法对车辆在道路上行驶质量的影响程度进行分析并用试验验证其可靠性,从而确定了铺装类型、技术等级、道路使用年份与路面平整度之间的定性关系,建立了路面行驶质量指数分布图。试验结果表明,该方法对于路面平整度的评估效果明显,符合实际。
For the establishment of China’s automobile road surface spectrum database, the relevant information of road surface roughness is needed. Therefore, based on the investigation of the basic conditions of roads in Jiangsu Province, the factors affecting the smoothness of the pavement are analyzed, and the technical grade of road, the years of road use and the pavement conditions of pavement are selected as the independent variables for predicting the road surface roughness. The Delphi method is used to analyze the influence of the vehicle running quality on the road and the reliability of the test is verified by experiments to determine the qualitative relationship between the type of pavement, technical grade, road use year and road surface roughness, Quality Index Distribution. The test results show that the method has obvious effect on the evaluation of road roughness and is in line with the actual situation.
