根据依留申小弹塑性变形理论，研究了结构形式为沥青面层、半刚性基层和土基的三层柔性路面体系。路面各层材料应力应变关系符合幂硬化规律且层间光滑接触。载荷图式为双圆或四圆垂直均布荷载。文中给出了柔性路面的应力及位移解析表达式，并给出了具体算例。
According to the small elastic-plastic deformation theory of Ilyushin, the three-layer flexible pavement structure whose structure is asphalt, semi-rigid and soil is studied. The stress-strain relationship of the pavement materials complies with the hardening law and the layers are in smooth contact. Load pattern for the double circle or four circles vertical uniform load. The analytical expression of stress and displacement of flexible pavement is given in this paper, and a specific example is given.
