摘要
该文综述了前人所作的工作内容,并借鉴了其研究方法。详细论述了动荷载下柔性路面基础动力响应有限元分析,分别介绍了建立路基响应计算模型的步骤、数值模拟计算、有限元模型建立、有限元网格细化研究、材料特性和本构关系及计算结果分析,最后给出了研究结论。
The article comprehends the working contents by the predecessors and uses their researching methods for reference. The article discusses in detail the finite element analysis of dynamic response of the flexible pavement foundation under the dynamic load, separately introduces the steps, numerical analog calculation, setting up the finite element model, detailing study of finite element network, analysis of the material characteristics, constitutive relations and calculation results. Finally, the article gives the study conclusion.
