The development of finite element technology makes it possible to elaborate the simulation calculation of pavement structure,but there is no unified conclusion on how to establish the finite element model in accordance with the reality by software.Based on this,the finite element models of three typical asphalt pavement structures on full-scale test track were established by using the large general finite element software ABAQUS,and the influences of model size,boundary conditions,load forms,mesh division and other parameters on the mechanical response results of pavement were studied.The theoretical values obtained by BISAR software were compared with the results by ABAQUS.The reasonable finite element modeling method and parameters are determined to provide modeling basis for the subsequent in-depth finite element analysis of asphalt pavement structure.
