The dissertation in hand is divided into two parts. In its first part the fundamental equations for the continuum mechanical description of the half-space are transformed into the wavenumber-frequency-domain. For this purpose, by the use of the potential approach according to Helmholtz and a fourier transformation, the latter will be converted into ordinary differential equations. The description of the half-space is based on the assumptions of a porous medium according to the Theory of Porous Media (TPM). The equations thus derived and their solutions will be put into relation with those of the classical one-component half-space. The second part takes up again the classical one-component half-space and describes the case of a dynamically loaded, in lateral direction rigid beam of infinite length on the surface of the half-space. For this reason particularly the influence of the displacement disability in lateral and longitudinal direction by the beam on the vertical component of the half-space displacement will be examined more closely. The beam’s connection to the ground is acquired by the so-called half-space stiffness, which reflects the continuum dynamic behavior of the ground. By the use of Legendre-polynomial-approaches to describe the interaction stresses the half-space stiffness will be determined in a semi-analytical way.
