| 摘 要： | 应用基于弹性层状体系理论的路面结构计算程序，分别以路表设计弯沉值、沥青面层层底拉应力为换算指标，变换沥青面层、级配碎石基层、土基结构层的厚度、模量等结构层参数，同时考虑不同轴距变化的影响，计算柔，陛基层沥青路面轴载换算公式中的轴数系数。通过对计算结果的分析发现，轴数系数与结构层参数密切相关。进一步回归分析大量计算结果并与我国设计方法中轴载换算公式中的轴数系数取值作对比分析，提出建议的轴数系数计算公式。

| Abstract: | Applying the program based on layer-elastic theory, changing the value of structure-layer parameter and wheelbase, the axle-number coefficient in the axle-load conversion formula for flexible-base asphalt pavement is calculated under the two different conversion guidelines of pavement deflection and stress under base. Through analyzing the results, it is found that the axle-number coefficient is greatly depended on the structure-layer parameters. And the recommended axle-number coefficient formula is given based on regression analysis of the calculation results and camparisons with the design methods used in China. |
