针对目前高速公路交通载荷研究的不足,首先基于高速公路收费数据建立了断面标准轴载累计当量轴次计算模型。在此基础上,结合路面技术状况检测数据,提出了高速公路未养护路段路面使用性能变化的分析方法,并建立了标准轴载累计当量轴次与路面使用性能变化回归模型。最后,以陕西省汉宁高速公路为例,计算得到了各断面上行和下行的标准轴载累计当量轴次,并求解和验证了货车轴载与路面损坏的回归模型。
Aiming at the shortcomings of the current research on expressway traffic load, firstly, a calculation model of axial equivalent total axle load of the section is established based on toll data of the expressway. On this basis, combined with the testing data of the technical condition of the pavement, the analysis method of the pavement performance changes of the unprotected sections of expressway is put forward. The regression model of the standard axle load equivalent equivalent shaft times and the pavement performance changes is established. Finally, taking the Hanning Expressway in Shaanxi Province as an example, the standard axial cumulative total equivalent shaft times of each section up and down are calculated and the regression model of the truck load and the road surface damage is solved and verified.
