  • In order to get the deformation characteristics of embankment over sloped weak ground with different weak layer properties, a numerical model was established based on the nonlinear finite element method. The orthogonal design was applied to evaluate the significances of influencing factors. The research results show that the elastic modulus and thickness of a weak layer are the decisive factors affecting vertical settlement and lateral deformation; the lateral slope of ground is an important factor aggravating embankment deformations; when the weaker layer locates on ground top, embankment deformations are significantly affected, especially on lateral deformation. Engineering measures based on weak layer properties, such as foundation treatment and lateral restraint should be adopted to eliminate the deformations.
