摘要

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%.

Abstract: To study the rutting of asphalt pavement, first, based on the vehicle-road interaction, a simplified model for the dynamic vehicle load caused by road roughness was established; then according to the data from creep tests of asphalt mixture, the parameters for the calculation of asphalt pavement rutting with the modified Burgers’ model, were obtained through fitting; finally, in combination with the observed temperature data and with the ABAQUS finite element software, the pavement temperature field was introduced and the calculation model was established for the daily rutting prediction in view of consecutive temperature variation. The rutting growth of asphalt pavement based on vehicle-road interaction under thermal effects was simulated, and the effects of the pavement temperature, the vehicle load and the vehicle speed on the rutting were parametrically analyzed. The results show that, the rutting depth increases by 6.5% when the vehicle-road interaction is considered, indicating this factor can’t be ignored in the asphalt pavement rutting prediction. Both the axle load and the pavement roughness are related to the rutting linearly. Under the same axle load, the higher the temperature is, the faster the rutting grows and the bigger the final rutting depth gets, and the rutting decreases with the vehicle speed. Moreover, at a vehicle speed where the resonant vehicle-road interaction occurs, the resulting rutting depth is 32% bigger than that in the case without this interaction.
