  3. 2. Processing of ERT data from Stabilised Columns

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Mårten Petersson; [2023]
    Keywords : inversion; ERT; quality control; jet grouting; aarhusinv; Technology and Engineering;

    Abstract : Modern construction sites are associated with high demands on suitable soil conditions, resulting in geotechnical challenges that can be solved using soil stabilisation techniques. The reliability of these techniques is tested using different quality assurance methods. READ MORE

  4. 3. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Edvin Nilsagård; Rebecka Knutsson; [2022]
    Keywords : ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE

  5. 4. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Jimmy Markström; [2022]
    Keywords : Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

    Abstract : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. READ MORE

  6. 5. Integration of geology with geophysics : Case studies from Svalbard

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Rylander; Anna Sterley; [2022]
    Keywords : Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Abstract : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). READ MORE
