摘要:
交通荷载参数是路面结构分析和设计中必须考虑的因素,建立参数数据库可为区域道路结构设计与分析提供参考依据。文章采用2013—2015年青银高速淄博段高速公路封闭式收费车道实测调查交通量数据,分析了交通量变化及轴载谱参数。结果表明: 3年总体交通量呈上升趋势,1类车所占比例最大可达72%,但所占比重呈现下降趋势,而2、3、9、10类车所占比例较大且呈现上升趋势;2、3和9类车平均轴数是定值,不随交通量改变而变化,而6~8和10类车轴数系数随交通量变化而变化;在4~10月份交通量大,重载车辆多,分别在5、8和10月达到峰值;单轴单胎轴重分布系数基本呈单峰特性,而整体式货车和半挂货车的单轴双胎、双联轴和三联轴轴重分布系数呈双峰特性。
Abstract:
Traffic load parameters are the factors that must be considered in the analysis and design of pavement structure. The database can provide reference for the design and analysis of regional road structure. Based on the survey of closed toll lane in Zibo section of Qingyin Expressway, traffic volume data from 2013 to 2015 are obtained and axle load spectrum parameters are analyzed. The results show that the overall traffic volume is on the rise in the past three years, the proportion of type 1 vehicles is the largest, reaching 72%, showing a downward trend, and the proportion of type 2, 3, 9 and 10 vehicles is larger and showing an upward trend; the average axle number of type 2, 3 and 9 vehicles is fixed value and does not follow the traffic. The number of axle numbers of 6, 7, 8 and 10 varies with traffic volume. Traffic volume peaks in May, August and October, respectively, and there are large traffic volume and heavy-haul vehicles in the section from April to October. The axle load spectrum of single-axle single tire is basically single-peak, while that of single-axle double-tire, double-coupling and triple-axle of integral truck and semi-trailer is double-peak; the axle load distribution coefficients of four axle types are slightly higher in three years.
