FLAC3D numerical simulation study on deformation of subgrade construction process

Yuxu Zhang

Abstract

Numerical simulation analysis of the deformation characteristics in the construction process of subgrade is conducted.In different unit weight and modulus of resilience conditions of filled soil,vertical settlement and the horizontal lateral displacement in the embankment slope feet of roadbed center change with the change of the depth of fill.The deformation law are found,which guide practical engineering of the sub grade construction.The filled soil of small severe is selected or the elastic modulus is raised to improve the settlement deformation of highway under the condition of standard requirement.
