Numerical simulation analyses of the highest reinforced embankment in Beizhang loess valley,Huozhou Town,Shaanxi Province,China,were carried out with finite element method.It is analyzed for the maximum and imum strains and stresses,shear stress,plastic zone of the highest embankment.The characteristics of strain and stress of high reinforced embankment and foundation are gotten,based on the comparison between reinforcement and non-reinforcement.The results show that the geo-grid not only enhance the stability of high embankment and foundation but also reduce its deformation.The FEM analysis results agree with the field tests.
