| Abstract: | In the paper,based on the multi-layer elastic system theory and nonlinear material constitutive model of granular cushion,the resilient moduli of granular cushion is analysed.Simultaneously,the computing program is designed and programmed,which computes the resilient moduli of special points in granular cushion.In addtion,the contour of the resilient moduli are drew in granular cushion.Eventually,finite element program is employed to carry out the linear analysis and nonlinear analysis of semi-rigid pavement with granular cushion. |
