摘　　要：为更深入了解超限作用下沥青路面结构的受力及破坏情况,并指导管理部门对相应路段采取合理的养护措施,根据路面结构的力学原理,以现行沥青路面设计规范为基础,分析并获得了车辆超限作用下沥青路面轴载换算公式。将该公式应用于超限作用下沥青路面验算系统,并将该验算系统与GIS相结合。研究结果表明:通过对系统数据和功能的需求分析对系统进行总体设计,即进行GIS相关软件的二次开发,得到基于GIS的公路超限运输沥青路面结构验算系统,以实现路网超限统计数据及路面验算结果的可视化,超限作用下路面结构验算过程的简便、直观化。To have a better understanding of stress and damage of asphalt pavement structure un- der overloading, as well as guide management departments to take correspondent maintenance measures, a new axial exchange formula for asphalt pavement structure under overloading was proposed by analyzing the related data based on the Specification for Design of Highway Asphalt Pavement and the principle of pavement structure mechanics. The formula was applied in the o- verloading checking system of asphalt pavement structure, and the checking system was combined with GIS. The results show that the system can be designed by requirements analysis of data and function of the system, that is, to further develop GIS related software, so as to obtain the As- phalt Pavement Structure under Overloading Checking System. This will make the checking sys- tem simple, convenient and direct, and the checking result visual. 3 figs, 11 refs.
