| 摘 要： | 基于线弹性力学和有限元方法，建立路面结构三维模型。计算垂直荷载、水平荷载及其组合作用下沥青路面力学响应，分析沥青路面表面开裂的机理。结果表明，沥青路面表面裂纹是水平荷载与垂直荷载组合作用导致的剪切或拉伸破坏，水平荷载是破坏的主要因素。

| Abstract: | Based linear elasticity theory and finite element method,the three-dimensional model of asphalt pavement structure is founded.Then the paper calculates the mechanical response to asphalt pavement of vertical load,level load and their coupled,analyzes the mechanism of asphalt pavement surface cracking. The result show the asphalt pavement surface cracking is caused by shearing or pull under horizontal load together with the vertical load,and the horizontal load is main factor. |

| Keywords: | horizontal load asphalt pavement surface crack shear stress tensile stress finite element method |
