| Abstract: | The paper adopts the finite element software ABAQUS,to establish the element model for the asphalt road surface structure with foundation cracks,calculates the stress strength factor of crack tips according to the collapsed singular isoparametric element and the fracture mechanics theory,and researches the influence of the road surface structural layer parameter on tip stress strength factor of cracks,so as to lay the theoretic foundation for the anti-crack design of roads. |
