| 英文摘要 | Pavement roughness in the highway greatly affects the performance of the subgrade structure. In this paper, a vehicles, roughness pavement, layered subgrade coupled dynamics analysis model is built considering the roughness of the pavement material. The roughness waveform of the pavement material is simplified to be a sine wave, and the vehicle is represented by two degrees of freedom. One of fourth vehicle model is used in the subgrade model. The vehicle load varying with the time is obtained using the vehicle model with consideration of the pavement roughness, which is applied in the numerical model. Finally, subgrade dynamic response and deformation values under the action of multiple cyclic vehicle loads are obtained. The comparison of pavement deformation between coupling calculation and non-coupling calculation is discussed. The study results show that, the deformation of the subgrade and pavement is related to the amplitude and wavelength of pavement roughness. In the interaction of the sunken position of the pavement and the vehicle load, a large deformation is produced. The variations of the pavement deformation are the same in different depths of the subgrade. It is also shown that the deformation of the pavement in coupling calculation and non-coupling calculation is different. The results suggest that it should be more realistic with consideration of the roughness of the pavement material. |
