| 摘要: |
| 为了更好地评价和预估沥青混合料抗车辙能力，基于离散元方法，应用PFC2D软件对沥青混合料的三轴剪切试验进行离散元数值模拟，并将模拟结果与实验室试验结果进行了对比分析.结果表明，离散元模拟结果与实验室试验结果具有较好的相关性，且规律一致，验证了模型的正确性；可基于此模型建立评价和预估沥青混合料抗车辙能力的虚拟试验方法. |

| Discrete Element Simulation on Tri axial Shear Test of Asphalt Mixtures |
|
|
| Abstract: |
| In order to evaluate and estimate rutting resistance of asphalt mixtures more conveniently, the softwear PFC2D was applied to simulate the tri axial shear test of asphalt mixture based on the discrete element method（DEM）, and the simulation results are compared with laboratory test results. Results show that the discrete element simulation and laboratory test have good correlation, which verifies the applicability of the model, while the virtual test method based on this model can be established to evaluate and predict the rutting resistance of asphalt mixtures. |
