长寿命沥青路面结构力学性能的三维有限元分析

Mechanical Performance Analysis of Perpetual Asphalt Pavement with 3-D Finite Element Method

长寿命沥青路面是目前国际道路工程界提出的新技术，是沥青路面界的研究热点。针对当前鲜有长寿命沥青路面结构在轮载作用下力学响应分布特点研究成果的现状，采用合理的网格划分方法，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，分析总结出长寿命沥青路面结构在轮载作用下力学响应分布特点，为长寿命沥青路面的设计与实践提供了理论参考。

Perpetual asphalt concrete pavements technique was presented newly by the international road engineering field and it was a hot issue in the field of international asphalt pavement.The there was rare production about stress character of perpetual asphalt pavement,a new mechanical performance analysis model was presented to analyze the stress character.A model is established on 3-D finite element analysis,which accompanies the scientific meshing method.And this model is applied to evaluate the typical perpetual asphalt pavement.The analysis results provide the mechanical theory of the design,construction and practice about perpetual asphalt pavement.
