Paper Title:
Numerical Analysis of Highmay under the Traffic Load
  Abstract

Based on the geometry irregularity of pavement, an expression of the traffic load was put forward. The influence law of design parameters of each part of highway and geometry irregularity of pavement on dynamic response of highway was discussed by the developed two-dimension finite element numerical analysis procedure. The research shows that the vertical maximum vibration acceleration of pavement and subgrade attenuates according to certain trend along depth direction in different work conditions; with the foundation stiffness increasing, the vertical maximum vibration acceleration of base course and cushion increases gradually, and that of pavement surface, subgrade and foundation decreases, and the decreasing amplitude increases gradually along the depth direction; the size of the influence of subgrade on dynamic response of highway is relevant to itself stiffness; the rational matching of all parts of highway can effectively reduce the vibration response; with the increase of geometric irregularity index, the vertical maximum vibration acceleration and maximum dynamic stress of pavement and subgrade increases significantly.
