| 摘 要： | 在有限元软件ABAQUS的平台上，应用python语言编制程序，研究了线弹性路面结构的动力响应、动态力学参数的反演方法以及影响反演计算的模型边界条件。在此基础上，结合某高速公路混凝土路面碎石化改建工程，采用有限元动力分析方法，对FWD实测数据进行反演计算，得到了较为合理的路面各结构层材料的力学参数，为改建路面的结构设计提供了参考。

| Abstract: | Based on the finite-element software of ABAQUS and Python Computer language,a program in this paper has been made to discuss the dynamic response of linear elasticity pavement structure,the way of back calculation dynamic mechanical parameters and the boundary condition of models which affects the results.On this basis,combined with a highway concrete pavement rubblization reconstruction project,using the finite-element dynamic analysis method,the measured FWD data has been used to back calculate the dynami... |
