运用无单元Galerkin方法对沥青混凝土路面的车辙深度进行了计算,分析了路面的不同结构类型、荷载大小和中面层模量及厚度对路面抗车辙性能的影响。在半刚性路面模型基础上,分析了不同节点布置方案对计算结果的影响。计算结果表明,半刚性路面的抗车辙性能较好,荷载和不同的中面层材料对沥青混凝土路面抗车辙能力有较大影响。因此,为了有效地防止车辙的产生,应该在路面设计时对中面层的抗车辙能力予以考虑。 The elemental Galerkin method was used to calculate the rutting depth of asphalt pavement. The influence of different structure types, load size, middle layer modulus and thickness of the pavement on the rutting resistance of the pavement was analyzed. Based on the semi-rigid pavement model, the influence of different node layouts on the calculation results is analyzed. The calculated results show that the anti-rutting performance of semi-rigid pavement is better, and the load and different middle-layer materials have a greater impact on rutting resistance of asphalt pavement. Therefore, in order to effectively prevent the generation of rutting, the anti-rutting ability of the middle layer should be taken into consideration when pavement design.
