Determination of characteristics of compacted sandy and clay soils using field and laboratory methods

   Currently, it is common to construct buildings and structures on foundation soils that are pre-compacted in various ways. At the same time, the physical and mechanical properties of the foundation soils change in order to increase the bearing capacity of the foundation soils of tasks and structures. This article describes the studies of the physical and mechanical properties of soils using the example of a number of construction sites. Some results from these studies before and after compaction are presented. Physical, deformation and strength characteristics were determined both in laboratory and field conditions.

   When carrying out the work, the following tasks were set: to conduct full-scale (field) and laboratory studies to reliably determine the characteristics of the strength and deformability of compacted sandy soils; analyze the characteristics of compacted soils, which determine the development of deformations over time; conduct experimental studies in field and laboratory conditions on the use of compacted sandy soils of various granulometric compositions and densities as the soil foundation of a structure; based on analytical studies, establish a set of controlled parameters of the properties of compacted soils.

   Thus, the object of study in this work was: sandy soils with different granulometric compositions.

   Conclusions were drawn based on the results of the work.
