Bohrprofils

Bohrprofils, also known as boring profiles or soil profiles, are graphical representations of the soil layers encountered during a drilling operation. They are essential tools in geotechnical engineering and geological surveys. A Bohrprofil typically displays the depth of the borehole on the vertical axis and the characteristics of each soil layer on the horizontal axis.

These characteristics can include the type of soil (e.g., sand, clay, gravel), its consistency or density, moisture content, and other relevant properties like the presence of groundwater or rock. The information is usually gathered through visual inspection of the soil samples brought up by the drill or through in-situ testing methods like standard penetration tests.

The purpose of a Bohrprofil is to provide a clear and organized record of the subsurface conditions. This data is crucial for various applications, including foundation design, excavation planning, and the assessment of potential geological hazards. Engineers use Bohrprofils to determine the suitability of the ground for construction projects, to estimate bearing capacities, and to plan for any necessary ground improvement measures.

Bohrprofils are often accompanied by a legend that explains the symbols and color codes used to represent different soil types and conditions. The accuracy and detail of a Bohrprofil depend on the drilling method used, the frequency of sampling, and the expertise of the personnel conducting the survey. They are a fundamental part of any site investigation report.
