An example of a preliminary analysis of the soil

Preliminary results of engineering-geological surveys contain information on:

  • classification of rocks (loam light or heavy, sandy or silty;
  • sandy loam silty, or sandy; the sand is fine, medium, etc.);
  • the consistency of clayey rocks;
  • humidity arenaceous rocks; classification of soils by development challenges. Also specifies the depth level of the groundwater table (at the opening). Below consider in more detail an example of the preliminary analysis of soil

Preliminary results of engineering-geological surveys in Pavlograd Dnipropetrovsk region

Based on the results of drilling in the study the thickness of sediments of 4 selected engineering-geological element. The numbering of the EGE adopted an independent. Description of the selected IEG follows:

  1. The layer t, is represented by the black loam of solid consistency with inclusions of gravel, gravel and construction debris. Lies across the area of study. The exposed layer thickness to 2.0 m. the Number of soil development challenges according to DBN D. 2.2-1-99 – 35 V.
  2. EGE 1A ar – Loam lightweight, black, semi-solid consistency, with inclusions of organic residues. Occurs throughout the study area, at depths from 2.0 to 3.0 m. the Number of soil development challenges according to DBN D. 2.2-1-99 – 35 V.
  3. EGE 1A ar – Clay light, sandy grey, jugoplastika consistency, with thin streaks of sand. Occurs throughout the study area, at depths from 3.0 to 4.0 M. the Number of soil development challenges according to DBN D. 2.2-1-99 – 35 b.
  4. EGE 2 e,vdPIII – the Sand is fine, crary, gray-yellow, medium density average degree of saturation and saturated. Occurs throughout the study area, at a depth of 4.0 to 5.0 m. the Number of soil development challenges according to DBN D. 2.2-1-99 – 29.
  5. EGE 3 ar – sandy loam sandy, gray, gray-yellow, fluid consistency. Occurs throughout the study area, at a depth of 5.0 m to 6.0 m. the Number of soil development challenges according to DBN D. 2.2-1-99 – 36.

In the period of geological engineering survey, engineering-geological workings were opened first from the surface aquifer in alluvial deposits. The depth of the groundwater level at the time of the survey 4.6 m. water-bearing rocks serve as fine Sands and sandy loam. Food of the aquifer is due to infiltration of atmospheric precipitation. Therefore, the ground water regime intermittent, depending on the time of year and rainfall. Unloading of the aquifer is outside of the site. Aquiclude exploration wells not opened.

According to DBN B. 1.1-24-2009 "Injenerniy Zahist territories that sporud from ptoblema zateplena" of the studied area is not flooded. In General, the survey area is in a stable state. More accurately the composition and physico-mechanical properties of soils will be determined in the stationary accredited geotechnical laboratory of the Dnipropetrovsk branch "Dneprogiprotrans" in Dnepropetrovsk.
