    Abstract
  • In order to analyse the post-construction settlement rules of high backfills adjacent to(abutment, ) a plane-strain numerical model was presented by ABAQUS/standard finite element code, the influence degrees of backfills parameters on settlement were studied.The simplified method is verified to be reasonable and feasible by making the comparison between the numerical analysis and field measure results because its computation result can indicate the rules and properties of backfills real settlement, some parameters, such as elastic modulus, permeability coefficient, unit weight and preloading time, are the major influence factors on the post-construction settlement of backfills.Perhaps the "bridge bump" is reduced while the mechanical characteristics of backfills and construction method are improved in design.
