摘要
文章采用有限元软件ANSYS建立车辙预估模型,分析不同轴载下及改变结构层厚度时旧水泥混凝土路面沥青罩面结构层的压应力、剪应力分布特点。计算分析结果表明,压应力是车辙形成的敏感因素和拟定结构层厚度的重要参考指标,同时罩面层抗车辙设计还需考虑剪应力的分布特点。
This article established the rutting estimation model by using the finite element software ANSYS,and analyzed the stress and shear distribution characteristics of asphalt overcoat structure layer of old cement concrete pavement under different axis load and when changing the structure layer thick-ness. Calculation results showed that the compressive stress is the sensitive factor for the rut formation and the important reference indicator to determine the structure layer thickness,while the overcoat layer anti-rut design shall also consider the shear distribution characteristics.
