The simplified 1D and numerical 3D FE models of the subsoil are presented. The main reason of this methodology is proposed the frequency dependent complex function or as a spring-dashpot system, with the spring becoming negative for certain frequencies, which cannot be directly implemented in standard structural analysis codes. The methodology of the calculation of the impedance functions due to dynamic excitation are considered.
