“…As a rule, in practice, in design solutions, the values of the compaction coefficient (Kcom) do not reach one, nevertheless, for the completeness of the experiment, soil compaction was carried out, including up to indicator 1. In parallel, control engineering and geological studies were conducted, the deformation modulus was determined [6][7][8].…”

Based on the data of physical and mechanical properties of soils obtained at various construction sites in Moscow, the article discusses in detail the issues of soil compaction and determination of bearing capacity. The article describes various methods of soil compaction, which must be taken into account to determine the value of the physical and mechanical characteristics of the soils laid down in the project. It is especially important at the initial stage to determine the necessary parameters of the compacted base. The described dependences of the deformation modulus and the compaction coefficient for the artificial base were carried out in comparison with engineering and geological data obtained from real objects in the city of Moscow. The analysis of the results obtained for sands with different granulometric composition was carried out and graphs of the dependencies of the data obtained were constructed. The article also describes the controlled parameters when using a compacted sand cushion as an artificial base.

“…12a and 12b present the variation of void ratio versus water content and suction, respectively. These figures are also referred to as shrinkage-swelling curves [86], reflecting the volumetric changes of the soil when its hydric condition changes. The shrinkage limit of water content (w SL ) is defined as the intersection of two asymptotes of the curves (dashed lines in Fig.…”

“…Ref. [26] demonstrated that the liquid limit significantly influences the shrinkage limit, air entry suction, and compressibility of compacted samples. Soil disturbance, often accompanied by changes in dry density due to the compaction or relaxation of cohesive forces between particles and aggregates, is another important parameter to consider, as disturbance can modify the pore space architecture [27].…”

Expansive soils commonly encountered beneath foundations often lead to structural issues inducing expensive repairs. With the increase of the frequency of dry summers and irregular rainfall patterns, the clayey and marly soils become more and more sensitive to shrinking and swelling phenomena. So to find solutions and improve the knowledge on such phenomena especially in temperate countries where the saturation state is considered as the usual soil state, the impact of the soil density on shrinkage was studied by varying the compaction mode and introducing a swelling step before shrinkage. As expected, dynamically or statically compacted clayey or marly soils exhibited high shrinkage deformation when the soil had a low density. The swelling before shrinkage impacted the soil structure but ultimately had a low effect on shrinkage deformation. Swelling deformation was also influenced by density; the denser the soil, the more sensitive the compacted soil became to swelling. Furthermore, compaction modes induced differences in swelling or shrinkage amplitude that couldn’t be explained by microstructural observations. Finally, results demonstrated that intact soil behavior after shrinkage could be extrapolated from swelling–shrinkage tests conducted on remolded soil samples, thus decreasing the cost of field investigations.
