摘　　要：为解决交通流轴载计算问题 ,本文分析了交通流的构成和分布 ,提出了分布轴载、车流轴载、单车平均轴载等新概念 ,提出了一套可行的完整的计算方法 ,并在与实际数据反复对比的基础上建立起沥青路面车流轴载模型。南京二桥路面管理系统首次利用该模型解决了如何使用称重站资料计算交通流轴载的问题 ,得到令人满意的结果。In order to calculate axial loads of traffic flow, this thesis analysed its structure and distribution, put forward several new concepts suth as distributive axis load, axial load of vehicle flow, average axial load of single vehicle and so on ,and put a complete set of effective method of calculation . On the base of repeating contrast to practical data we created the model of axial load of vehicle flow for bituminous pavement. For the first time we applied this model on the Pavment Management System of Nanjing Second Yangtze River Bridge(NEPMS), and solved the problems how to use the data of the weighing station of the bridge, and how to calculate the axial loads of the traffic flow, with satisfied results.
