Calculation of the effect of seismic loads on earth dams by the linear spectral method

The preceding calculation schemes and corresponding numerical results show that the available information on the properties of soil materials and methods of calculation (solutions of static and eigenvalue problems for a linearly elastic medium on the basis of the FEM, interaction of an oscillator with a half-plane, etc.) permit evaluating the seismic stability of earth dams within the scope of the standard method with approximate consideration of the most characteristic features for such structures (nonlinear deformability and saturation of the material, interaction with the foundation).
