boreholetutkimusten

Boreholetutkimusten, a Finnish term, translates to "borehole investigations" or "borehole studies" in English. These investigations are crucial in various fields, primarily in geology, hydrogeology, and civil engineering, to understand subsurface conditions. They involve drilling a narrow hole into the ground, called a borehole, to extract samples and gather data about the soil, rock, and groundwater present.

The primary purposes of boreholetutkimusten include determining the geological stratigraphy, identifying different soil and rock layers, and assessing their physical and chemical properties. This information is vital for tasks such as planning construction projects, locating mineral resources, assessing groundwater availability and quality, and investigating potential contamination sites.

Various methods are employed during boreholetutkimusten. Core drilling extracts intact cylindrical samples of the subsurface material, allowing for detailed laboratory analysis. Drilling with augers or other methods can provide disturbed samples or direct in-situ measurements. Geophysical methods, such as resistivity or seismic surveys, can also be conducted within boreholes to infer properties of the surrounding rock or soil without direct sampling.

Data obtained from boreholetutkimusten helps engineers and geologists make informed decisions regarding foundation design, slope stability, water resource management, and environmental remediation. The accuracy and comprehensiveness of these investigations directly impact the success and safety of numerous projects.
