Abstract

To further investigate the variation of stress under moving traffic loads in tunnel entrance and exit area, in this paper, a 3-D finite model(FE) of the pavement structure in entrance and exit section was established. The pavement of the tunnel consists of asphalt concrete and cement concrete. The viscoelastic property of asphalt mixture and the damping effect of the structure were considered. Dynamic traffic loads was applied during simulation. It is shown that the maximum interlayer shear stress between AC and PCC in the entrance and exit area of the tunnel was 28.37% larger than that of the regular pavement in the tunnel, which may be caused by the low cohesion between AC and PCC layers in the entrance and exit area of the tunnel.
