| 摘 要： | 路基路面各层的材料性质、参数等均对弯沉的大小产生很大影响.通过分析土基模量及沥青路面各层参数对路表弯沉的影响,结果表明土基模量是影响路表弯沉的最重要因素,它的大小决定了其他参数对路表弯沉的影响程度.

| Abstract: | The deflection size is affected by the material properties and parameters of the pavement and subgrade.This paper analyzes the impact on surface deflection by subgrade modulus and each layer parameters of asphalt pavement.The result shows that the subgrade modulus is the most important factor that affects road surface deflection,which determines the influence degree on road surface deflection by other parameters. |

| Keywords: | structure subgrade modulus surface layer parameter road surface deflection |
