Abstract:

In order to study the embankment reinforced with Horizontal-Vertical (H-V) reinforcement under traffic loading,  a two-dimensional model was calculated by finite element method (FEM) program ABAQUS using dynamic explicit. According to the result of dynamic triaxial tests, fitting strainsoftening curve was written into user subroutine in ABAQUS. The deformation and strain of the embankment without reinforcement, with ordinary reinforcement and
with H-V reinforcement were analyzed and compared. The H-V reinforcement significantly reduced the strain, vertical displacement and horizontal displacement and controlled differential settlement in embankment under traffic loading. H-V reinforcement had a better reinforced effect than ordinary reinforcement, especially in the control of horizontal displacement.

Key words: embankment, Horizontal-Vertical (H-V) reinforcement, traffic loading, strain-softening, finite element method (FEM)
