Figure 3: Types of half-space and their classification. According to the Frölich formula in [7], a relation is proposed based on the condition of minimum deformation work. If = 3 it is an elastic isotropic half-space (E = const.) and if = 4 it is a half-space whose modulus of deformability increases linearly with depth depending on E 0 - the modulus at the surface, z-coordinate (depth) and coefficient m dependent on Poisson coefficient . Modulus of deformability increases linearly with depth according to Eq. (1) shown in [7]:

Fig. 4 and Tab. 1 shows a model of an inhomogeneous half-space, in which the deformability module increases with increasing depth of the subsoil model (in layers).
