Determination of the characteristics of compacted sandy soils by field and laboratory methods

Nowadays, it is a common practice to erect buildings and structures on base soils, which were previously compacted in various ways. During this process, the physical and mechanical properties of the following base soils are changed in order to increase their bearing capacity. In this article, on the example of some construction sites, test studies of the physical and mechanical properties of soils are described. Some results of these studies, both before and after soil compaction are given. Physical, deformation and strength characteristics were determined in both laboratory and field conditions. During the work, the following objectives were set: to conduct full-scale (field) and laboratory studies aimed at reliable determination of the strength and deformability characteristics of compacted sandy soils; to analyze the characteristics of compacted soils that determine the development of deformations over time; to conduct experimental field and laboratory studies on the use of compacted sandy soils of various granulometric composition and density as the structure base; to establish a set of controlled parameters of the compacted soils properties on the basis of conducted analytical studies. Thus, the object of the study during this work was sandy soils with different granulometric composition. The conclusions were drawn on the results of the work.
