摘要

摘要我国沥青路面设计尚未考虑交通量的季节分布系数。通过对评价数据和影响不同地区交通量月分布系数的因素进行综合分析,利用BP神经网络算法预测并确定了哈尔滨市交通量月和季节分布系数。研究内容包括交通量月度分布系数的数据调查和分析,分析影响上述系数的因素,预测和确定交通量月度和季节分布系数,以及这些系数的应用等,对一年中的季节交通量进行了计算,应用结果表明,交通量的季节分布具有科学合理性。此外,本研究表明,季节交通量可以准确地评估路面轴载的实际情况,从而使沥青路面设计更加合理。最终,这些发现可以适当地满足在路面上通过的实际车辆载荷的要求。

Determination and application of seasonal distribution coefficients of traffic volume in pavement design
ABSTRACT The seasonal distribution coefficients of traffic volume have not been yet taken into account in asphalt pavement design in China. Through comprehensive analysis on the assessed data and the factors affecting monthly distribution coefficients of traffic volume in different areas, the monthly and seasonal distribution coefficients of traffic volume in Harbin city, China has been predicted and determined using a back propagation (BP) neural network algorithm. The research contents involve data investigation and analysis of monthly distribution coefficients of traffic volume, analysing the factors affecting the mentioned coefficients, prediction and determination of monthly and seasonal distribution coefficients of traffic volume, and application of those coefficients, etc. Through the application of monthly and seasonal distribution coefficients, the seasonal traffic volumes in a year were calculated, and the application results demonstrated that the seasonal distribution of traffic volume has a scientific rationality. In addition, this study indicated that the seasonal traffic volume could accurately evaluate the actual conditions about axle loads on the pavement, resulting in the asphalt pavement design to be more rational. Eventually, the findings could appropriately meet the requirements of actual vehicle loads passing on the road surface.
