  1. 1. 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

  3. 2. What has happened on Swedish mires? The effects of drainage on vegetation changes over recent decades

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anna Ljungqvist; [2022]
    Keywords : peatlands; mires; bogs; fens; sweden; vegetation; plant ecology; time trend; data; nfi; nils; climate change; global warming; mosses; sphagnum; afforestation; trees; wetland; presence; coverage; drainage; ditch;

    Abstract : As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. READ MORE

  4. 3. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Axel Barrdahl; [2022]
    Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE

  5. 4. Buckling of Short End-Bearing Piles in Clay

    University essay from KTH/Jord- och bergmekanik

    Author : David Ebenhardt; Jonas Stener; [2022]
    Keywords : Short piles; buckling; elastic buckling length; initial deflection; finite element method; Eurocode 3;

    Abstract : Structural design of piles with respect to buckling in Sweden is commonlymade in accordance with the calculation model from the Commission ofPile Research, PKR. A prerequisite for this model is that the elasticbuckling length of the pile is shorter than the physical length. READ MORE
