simultaneously are 0.99148 and 0.00682 respectively. The statistical results show the apply multidirectional seismic loading to the embankment-subsoil model has better results quality. The statistical model of the several stages of the numerical simulation show the vibration mechanism, differential displacement, and nonlinear deformation of the embankment-subsoil model. The uses of the single stage of the numerical simulation for the seismic analysis of the embankment-subsoil is not able to depict the vibration mechanism, differential displacement, and nonlinear deformation of the embankment-subsoil.
