Pavement Rutting Analysis Based on Vehicle-Road Interaction Under Thermal Effects

  • 摘要: 研究沥青路面结构的车辙问题,首先基于车辆与路面的相互耦合作用,建立路面不平整度引起的车辆荷载简化模型;然后根据沥青混合料蠕变试验数据,拟合出基于修正Burgers模型的沥青路面车辙的计算参数;最后结合气温观测数据,借助ABAQUS有限元软件,引入路面温度场,建立了考虑连续变温的日车辙预估计算模型.模拟了考虑车辆路面相互作用的沥青路面在连续变温条件下的车辙变化规律,并分析研究了温度、车辆荷载以及车速对车辙的影响.结果表明,考虑车辆路面相互作用得到的日累积车辙深度增大了6.5%,说明这一因素对沥青路面车辙的预测是不可忽略的;轴载及路面不平整度均与车辙量线性相关;而相同轴载作用下,温度越高,车辙增长越快,得到的车辙量越大;随着车速增大,车辙深度呈减小趋势,并且在车辆与路面发生共振的车速下,该文模型得到的结果增大了32%.
