摘要
针对长寿命沥青路面结构,采用合理的网格划分方法,建立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,分析总结轮载作用下长寿命沥青路面结构层底拉应变分布特性及变化规律,为其设计理论与设计方法的研究提供理论参考。
This paper, aiming at long lifetime asphalt pavement structure, establishes three-dimensional finite element model for mechanical response of the long lifetime asphalt pavement strueture by adopting the reasonable meshing methods, analyzes and summarizes the tensile stress-strain distribution properties of the layer bottom and variation laws of long lifetime asphalt pavement structure layer under the wheel load to provide the theoretical references for design theories and design methods of the long lifetime asphalt pavement.
