| 摘 要： | 弹性层状体系理论,是当前国内外广泛使用的描述沥青路面结构的力学模型。以此模型为基础,采用大型通用有限元软件ANSYS分析轮载作用下沥青路面的弯沉分布状况,研究弯拉应力的变化规律,得出最大弯沉点在轮载中轴处的结论;同时揭示了面层层底不一定总受拉,受面层刚度和厚度影响,有时也有受压的规律。说明有限元实体仿真分析在路面结构分析中具有广泛前景。

| Abstract: | Theory of multi-layer elastic system is a mechanical model widely used around the world to describe structures of asphalt pavement.Based on the model,the deflection distribution of asphalt pavement under tyre load was analyzed with the large generally used finite element software ANSYS.And the change rules of bending tensile stress were studied,which lead to some valuable conclusions. |
