摘　　要：基于智慧高速营运数据采集系统和轴载原始记录等数据,提出了交通计重收费荷载的采集要素与校验方法,建立了无效数据清洗原则、基于贝叶斯理论的交通荷载参数计算模型、缺失轴载数据挖掘方法,得到了当量设计轴载累计作用次数,客观和精确地反映了交通荷载特性,为路面结构设计、养护与营运工作提供更精确、客观的交通荷载特性数据。Based on the data of intelligent high-speed operation-data collection system and original records of axle load,this paper proposes the collection elements and verification method of traffic toll-byweight load,establishes the principle of invalid data cleaning,the calculation model of traffic load parameters based on Bayesian theory and the data mining model of missing axle load,obtains the cumulative equivalent axle load action times,objectively and accurately reflects the traffic load characteristics.It provides more accurate and objective traffic load characteristics for pavement structure design,maintenance and operation.
