摘要
通过建立基于粘弹性理论有限元模型,对标准轴载作用下排水性沥青路力学响应进行研究,对不同厚度下路面力学分布规律、温度应力对排水沥青路面影响、半刚性基层裂缝在排水性沥青路面内扩展情况等进行了计算,并以计算结果为依据从优化排水性路面结构、防止循环温度荷载对路面破坏、路面抗裂性能等角度出发对排水性沥青路面的厚度进行了推荐。
This paper study on the stress response of OGFC pavement under standard axle load through establishing finite element model. The stress response of pavement with different thickness and temperature stress were calculate to evaluate the influence from traffic capacity,temperature and resisting crack reflection. Based on the computed resulted, the reasonable thickness of OGFC pavement was defined with considering traffic ,temperature and resisting crack reflection.
