Determination of Ultimate Filling Height of Slag Subgrade with FEM Modelling

Abstract:

To use slag in high subgrade reasonably and effectively, the filling height limit was investigated. The viscoelasticity parameters of slag in a ascertain graduation were gained by viscoelasticity constitutive model and indoor creep test. The differential settlement values (DSV) of subgrade surface at various filling heights were obtained by the finite element modelling. The research results show that the DSVs on subgrade surface increase with the filling height. According to the effects of DSV on pavement structures, four grades of differential settlement from low to high were divided, the ultimate filling heights of slag were evaluated correspondingly.
