基于抗裂考虑的排水性沥青路面应力响应研究

Stress response research on drainage asphalt pavement based on crack resistance thinking

通过建立带有基层裂缝的有限元模型,分析了荷载位于裂缝边缘处时路面应力分布规律,并对不同面层下裂缝处应力分布规律进行研究,得出了路面厚度与裂缝处应力大小的关系。

Through setting up finite element model with foundation layer crack,it analyzes the pavement stress response distribution law for the load lying crack edge,studies the crack stress distribution law under different surface layer,and obtains the relationship between pavement thickness and crack stress.
