embankment. At the toe of the embankment, the size of the mesh was adjusted according to the toe geometry of the embankment and size of the mesh maintained with maximum level to be a hexahedral shaped mesh type.

Figure 4 illustrates the mesh after the assembly of the embankment and subsoil for developing a model. Figure 4 explains the boundary condition of the embankment-subsoil when the near-fault ground motion was applied to the embankment-subsoil model in a single direction and multidirectional. The embankment first time is subjected to near fault ground motion in the single direction and in the second time the embankment-subsoil was subjected to the multidirectional.

The mechanical properties of the soil are important in stress-strain response analysis of the embankment-subsoil model for prediction of the seismic stability of the embankment constructed in a territory highly subjected to the high magnitude and devastative earthquake. And in construct an embankment uses the local material is an economical advantage and leads to a reduction of construction time. In this study, the mechanical properties for soil used in the embankment and subsoil are same and the modulus elasticity of the equal 20 (MPa), the maximum friction angle of the soil is selected equal to 30 (deg), the dilatancy angle equivalent to zero (deg), the cohesion of the soil equivalent
