Research on Influence of Longitudinal Gradient to Rigid Base Composite Road of Cross River (Sea) Tunnel under Large Longitudinal Slope

Abstract:

The influences of longitudinal gradient on the large longitudinal slope rigid base composite road of cross river(sea) tunnel are concerned recently. Then the relationships between sheering stresses versus slope angle, load, pavement depth, interlayer touch condition and modulus are discussed separately by a three dimensional FEM model. Calculation and analysis showed: gradient had great influence on the surface tangent load and little influence on design deflection, the base and surface.The maximum tension and sheer on surface were increased with the gradient. On general, the gradient and surface tangent load should be considered in structure analysis for the large longitudinal slope road.
