“…It is shown that the fractal dimension of the particle size distribution s D and pore size distribution p D (see below for definitions) have an important role in modeling of soil compression. Widespread loess soils may be considered as a discrete medium [12][13][14]. Under increasing humidity subsidence degradation occurs as a result of the slow disintegration of micro-aggregates into free particles, repackaging and porosity changes.…”

Loess soils may be considered as a discrete medium. Under increasing humidity subsidence degradation occurs as a result of the slow disintegration of microaggregates into free particles, repackaging and porosity changes. The volumetric porosity of the formed new structure and the volumetric porosity changes can be quantified from the position of the fractal theory. The main aim of this paper is to show that the fractal dimension of the particle size distribution function has important role in the description of the subsidence degradation from the standpoint of a new approach to the evaluation of soil subsidence. For approbation of our theoretical propositions we studied subaerial eluvial-diluvial and eolian-diluvial loess soils of Pleistocene age in the outskirts of Dnipropetrovsk. The value of is correlated with the amount of free particles, it is influenced by the genesis because is less in loess horizons than in paleosoil. Minimum of the fractal dimension of the particle size distribution function is obtained with aggregative method of preparation in which decomposition of aggregates is less expressed.
