普通国省干线重载交通道路轴载谱快速实测技术及应用

Technology and application of rapid measurement of axle load spectrum of heavy traffic road in ordinary national and provincial trunk highway

介绍了道路轴载谱快速实测系统组成及工作流程,分析了道路轴载谱快速实测技术的影响因素,并通过对实际道路轴载大数据的深入挖掘,分析了检测时间点和时间段(检测持续时间)对数据代表性的影响。结合山东省某重载交通省级干线公路,阐述了道路轴载谱快速实测技术的实际应用,对该道路路面结构进行了分析,提出了相应的设计建议。

The paper introduces the composition and workflow of the rapid measurement system of road axle load spectrum and analyzes the influencing factors of the rapid measurement system of road axle load spectrum,and through the in-depth mining of the axle load large data of the on-site highway.The influence of detection time and time period(detection duration)on representative data is analyzed.Combined with a heavy load national and provincial trunk highway in Shandong province,the paper describes the practical application of the rapid measurement technology of road axle load spectrum.Then the paper analyzes the pavement structure of the highway,and proposes the corresponding design suggestions.
