#### 2.2.5 Calibration of the Subsoil Numerical Model--Partial Models
For area E, where for technical reasons the SDMT test could not be performed, calculations in variant 5 were not carried out. Finally, the parameters listed in Table 4 were adopted in calculations. \begin{table}

The analysis was divided into computational steps in which the phases of constructing the building were subsequently mapped, as described in Table 1 In the first step, _Geostatic_, the state of stress was introduced into the subsoil. In the second step, _Footing_, the geometry of the foundation and wall section were introduced. Then, in the next four steps, _Load 0_ \(\div\) 3, the load was increased in accordance with its values measured during the subsequent geodetic surveys. The load was applied in the form of an even pressure in the upper plane of the wall, calculated proportionally from the stresses in the area at the contact point between the foundation and the subsoil from the numerical model of the whole object. The procedure of calibrating partial models is described in detail in [62]. The results of the calculations were displacements and stresses in particular construction phases. The shape of the isolines in maps of stresses and displacements differed slightly for various parameter variants. In turn, the values of vertical displacements were significant. Selected bitmaps for the Z1 model are shown in Figure 13.  
The calculation results for all models and parameter variants are compiled in Table 5. The values of displacement were given in relation to the _Load 0_ step, so that they could be compared with geodetic measurements. Differences between calculated and measured values were also given. Positive values (green) mean that the calculated settlement was larger than the actual settlement, while negative values (red) mean that calculated settlement was smaller than the actual settlement. The largest displacements were obtained in calculation variants with parameters determined from oedometric tests (_EDO1_ and _EDO2_).
