Abstract
The article highlights results of the geotechnical analysis of the stress and strain state for the base of a subsoil massif under its interaction with the strip foundations. The massif is represented by loess soils which while soaking give overtime subsidences that complicate the operation of a building or a structure. Through geotechnical iterative research, optimization of the parameters for strip foundations on four axes at a four-storeyed residential building is carried out. Checks are performed on two groups of limiting states for scenarios of soil occurrence in natural, moistened and compacted states. The optimum dimensions in the width of strip foundations are selected, they give approximately the same strain values of the base after the creation of the soil bedding with its layer-bylayer compaction. The relevance of this research is to develop optimal parameters in the design of strip foundations for shallow depth on subsidental loess soils.
Highlights
Geomechanics, as a science, combining the mechanics of rocks and underground structures tends to analyze workings and structures that lie in sufficiently hard rocks at deep depths [1]
Given all the differences between these varieties of Earth science, one should determine the main conceptual feature that unites them. It is the principle of the interaction between feats of engineering and the natural environment which is rock or subsoil massif [4]. It is the diversity of soil and rock conditions that by Protodyakonov's scale are in range f = 0.5 ... 50, dictates the adoption of geotechnical or geomechanical tools which will fully enables the interaction of the engineering structure and the underlying or surrounding massif
In the case when strata of the subsidental zone is large, the foundation is placed in this layer, but measures are being taken to compact with heavy rammers, jet grouting piles, or practice cutting the loess soil and its replacing with stronger soils or by these loess soils by smaller strata with layer-by-layer compaction

Given all the differences between these varieties of Earth science, one should determine the main conceptual feature that unites them It is the principle of the interaction between feats of engineering (from mines at considerable depths [3] to foundations of shallow depth [2]) and the natural environment which is rock or subsoil massif [4].
