Numerical Simulation on Stress Transmission under Vehicle Load for Western Expressway

Abstract:

Based on the typical Pavement-Subgrade structure form of western expressways, the interaction of the Pavement-subgrade system under vehicle load is researched. The model of stress transmission is established through numerical simulation. The vehicle load transfers stress to subgrade surface via the pavement structure layers. According to the different properties and functions of pavement layers, similar pavement layers are combined into equivalent structure layers. In this study, stress distribution of vehicle load on subgrade surface is analyzed according to the different degrees of thickness and stiffness of the equivalent structure layers. Also, the effect of different subgrade fillers on stress transmission is studied.
