  1. 1. Utökad utvärdering av CPTu-resultat

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ludvig Danfors; [2022]
    Nyckelord :Soil Behaviour Type; CPTu; CONRAD; signalbehandling;

    Sammanfattning : In Sweden, it is common to use the CPT - Cone Penetration Test when probing in loose soils. This is mainly because the method is suitable for further assessment of soil layer sequences, pore pressure and forming an estimate of the geotechnical properties in-situ. LÄS MER

  3. 2. Integration of Borehole, Ground, and Airborne Data to Improve Identification of Areas With Quick Clays in Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Oskar Rydman; [2021]
    Nyckelord :TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Landslides; Frastad; TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Jordskred; Fråstad;

    Sammanfattning : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. LÄS MER

  4. 3. CPTu Configuration Impact on Evaluated Undrained Shear Strength

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Mårten Mjöberg; Axel Stenfors; [2020]
    Nyckelord :Cone Penetration Testing; Fields trials; Soil mechanics; Evaluated undrained shear strength.;

    Sammanfattning : This thesis evaluates the commonly used geotechnical probing method CPTu, on how different probe configurations impact the resulting evaluated undrained shear strength in soft clay deposits, in comparison to each other and laboratory methods. This is done by performing field investigations on Lindefältet, Södermanlands län, Sweden. LÄS MER

  5. 4. Evaluation of SCPT-surveys as method for accessing dynamic modulus

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Joakim Granskär; [2018]
    Nyckelord :SCPT; Dynamic modulus; Seismic surveys;

    Sammanfattning : The purpose of this master thesis is to evaluate the results from the completed SCPT (Seismic Cone Penetration Test) surveys with respect to the methods ability to estimate dynamic young´s modulus. This has been done by comparing the result from SCPT to other seismic methods and dynamic parameters converted from “static” geotechnical surveys. LÄS MER

  7. 5. Quality of CPTU : Analyses and comparison of data from commercial actors in Stockholm/Mälardalen

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Caesar Kardan; [2015]
    Nyckelord :CPT; CPTU; cone penetrometer; cone resistance; friction sleeve; pore pressure; undrained shear strength; conrad; CPT; CPTU; sond; spetsmotstånd; mantelfriktion; portryck; odränerade skjuvhållfasthet; conrad;

    Sammanfattning : CPTU is one of the most sophisticated geotechnical investigation methods. However, there is a large amount of uncertainties related to this method. The uncertainties depend on different types of factors, for instance lack of accuracy in performance and equipment. LÄS MER
