摘　　要：随着港口规模的发展,港口道路交通量不断增加,随之而来的超载超限问题越来越严重。为了给路面结构设计提供可靠的实际道路交通情况,需要进行现场调查交通量和轴载情况。本项目采用动态称重系统在港口附近道路做了实际轴载调查,统计分析了该路段上车辆的主要轴型分布比例并计算出设计车道上的累计标准轴次,根据规范规定判定调查路段的交通等级。依据我国道路设计规范,将各轴型的轴重转换为当量单轴轴载并绘制轴重分布图,分析车辆轴载在各区间上的占比,由此证明港口道路单轴当量轴重远大于我国公路轴限。With the development of the port scale, the traffic volume of the port is increasing, and the problem of overloading and exceeding the limit is becoming more and more serious. In order to provide a reliable and practical road traffic condition for the pavement structure design, it is necessary to investigate the traffic volume and axle load situation in the field. The project uses dynamic weighing system to do the actual axle load survey on the road near the port. The main axle type distribution ratio of the vehicle is statistically analyzed, and the cumulative standard axle times of the design lane are calculated. According to the regulation, the traffic level of the investigation section is determined. According to the code of road design in China, the axle load of each axle type is converted to the equivalent single axle load and the axle load distribution map is drawn. The proportion of vehicle axle load on each interval is analyzed, which proves that the axle axle equivalent axle load of port road is much larger than that of our country＇s highway axle limit.
