- The general tendencies in the distribution of concentration and water head fields in the consolidating soil massif modeled within the framework of the presented fractional-fractal model is generally in concordance with the tendencies in the distribution of similar fields obtained using the fractional-differential model [9,24] that takes into account memory effects, but not fractal properties of the medium, as well as with the classical consolidation model [2].
- A decrease of the fractal dimension for results in both an acceleration of salinization processes in the compacting massif (Figure 2a), and an acceleration of water head dispersion in it (Figure 2b), that is, to a reduction of the compaction time compared to the case when the process is described by the fractional-differential model that takes only memory effects into account [24].
- With an increase of the fractal dimension for , the processes of salinization (Figure 3a) and water heads dispersion (Figure 3b) significantly slow down compared to the case when these processes are modeled using the fractional-differential mathematical model [9,24], which indicates the presence of sub-diffusion properties in the presented fractional-fractal consolidation model.
