摘要
选取合理的路面结构与参数取值范围,采用有针对性的网格划分方法,建立了科学的长寿命沥青路面结构力学响应三维有限元分析模型;并以典型长寿命沥青路面结构为对象,分析总结出结构参数变化时长寿命沥青路面力学响应的变化趋势。
A new mechanical performance analysis model is presented to analyze the perpetual asphalt concrete pavements stress character. The model was established on 3D finite element analysis, which accompanies the scientific road structure, range of material parameter and meshing method. This model was applied to evaluate the typical perpetual asphalt pavement, and the mechanical response tendency with the variety of the structure parameters was analyzed.
