  1. 1. 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

  3. 2. Evaluating the Undrained Shear Strength of Sulphide-Bearing Soils in the Sundsvall Area

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Gustaf Holm; [2022]
    Keywords : Clay; cone factor; CONRAD; CPT; fall cone; field vane test; reduction; CONRAD; CPT; fallkonförsök; konfaktor; lera; reduktion; vingförsök;

    Abstract : Sulphide soils in Sweden are mainly found along the northeast coastline. These soils area characterized by their fine grain size, low shear strength and black, or grey, color. These soils are also found further south, in the Sundsvall area in Västernorrland, but have slightly lower sulphide content there. READ MORE

  4. 3. Probabilistic settlement analysis for embankments using preloading without surcharge

    University essay from KTH/Jord- och bergmekanik

    Author : Karl Escher; [2022]
    Keywords : Bayesian statistics; uncertainty; geotechnical risk evaluation; preloading; consolidation; embankments; ground improvement; dependence modelling.;

    Abstract : Preloading without a surcharge is a common method for ground improvement. Thereare however uncertainties related to the number of site investigations and the partialfactor method has been identified as a problem. READ MORE

  5. 4. 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

  6. 5. Re-processing Reflection Seismic Data at a Quick-clay Landslide Site in Southwest Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Zhaochen Mu; [2022]
    Keywords : reprocess; reflection seismic; tomography; quick-clay; landslide;

    Abstract : This MSc thesis reprocessed seismic data collected at a site near the Gota River in 2011, focusing on two lines. The two seismic lines ran through a landslide scar zone for a total length of 1 km, both of which used dynamite as the seismic source. READ MORE
