    Abstract
  • In order to analyze the mechanics mechanism of reducing differential settlement at the transition section between abutment and embankment by means of reinforced backfills, the field sizes of centrifugal modeling tests were referenced, a plane-strain numerical analysis model of reinforced backfills behind abutment was established by ABAQUS finite element method, the influence factors of different reinforced design parameters such as spaces, lengths and rigidities of geogrids, strength of backfill material and stiffness of subsoil were analyzed, and the deformation behaviors of reinforced backfills behind abutment were studied. Analysis result indicates that the surface settlement of backfills behind abutment can be reduced effectively by reducing the spaces of geogrids, or increasing the elastic moduluses of geogrids, the inner friction angles of backfill material and stiffness of subsoil, or adopting the inverse-triangle variable-lengths reinforced layout of geogrids; however, the influence of subsoil stiffness on the deformation behaviors of reinforced backfills depends on the interaction characters between subsoil and reinforced backfills.
