| Abstract: | The three-dimensional dynamic finite element method(FEM) is adopted and a three-dimensional simulation model for asphalt concrete pavement with subgrade based on cross-anisotropy under mo-ving load is established by the large-scale finite element analysis software ABAQUS.The moving load has been implemented into ABAQUS code as user subroutines Dload and Utracload.The response of the stress in the pavement structure is got by using ABAQUS/Standard code.The simulation analysis results under the common speed a... |
