Title: 3D Finite Element Analysis on Asphalt Pavement Dynamic Response under Moving Load
Abstract:The asphalt pavement of newly-built roads in China adopts the double group uni-axle load 100 kN(BZZ-100)as the standard axle load,which is designed by the multi-layer flexible design theory under the ...The asphalt pavement of newly-built roads in China adopts the double group uni-axle load 100 kN(BZZ-100)as the standard axle load,which is designed by the multi-layer flexible design theory under the effect of double-circle uniformly distributed load.But the load that vehicle imposes on the road surface is the moving load.FEM analysis on the dynamic response of road surface in the cases of vehicle running at common speed and at the state of baking is carried out,through establishing the three dimensional dynamic FEM model of semi-rigid surface pavement.The time course curves of the vertical displacement,the vertical stress,the horizontal stress,the vertical shear stress and the horizontal shear stress of nodes at different depth which is underneath the load are obtained.The calculation results are compared with those under the static load.Read More
