Analysis of Dynamic Deviator Stress of Reinfored Subgrade under Traffic Loading

Abstract:

In order to study the influence of reinforcement on the distribution of dynamic deviator stress along the depth of subgrade, reinforced and unreinforced subgrade of graded-broken-stone-based asphalt concrete pavement under traffic loading was modeled by implicit dynamic FEM. Analytical results show that reinforcement can improve the vertical compressive stress distribution, and decrease shear stress transmitted to the surface of subgrade. The deviator stress on the upper part of reinforced subgrade is reduced distinctly, which is one of the key factors that can cause residual deformation. Therefore, reinforcement can restrain the development of residual deformation of subgrade induced by traffic loading.
