  1. 1. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

    M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Claes Sjöberg; Jens Kårhammer; [2021]
    Nyckelord :strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Sammanfattning : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. LÄS MER

  3. 2. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    Master-uppsats, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Joanna Ghaderidosst; [2020]
    Nyckelord :Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Sammanfattning : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. LÄS MER

  4. 3. Determination of dry density in tailings with a Dynamic Cone Penetrometer :

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

    Författare :Patrik Hagström; [2017]
    Nyckelord :dynamic cone penetrometer; tailings dam; tailings beach; tailings;

    Sammanfattning : Today mines produce metals which are used for everyday products by people worldwide. When metals are produced, waste products known as tailings are generated. These tailings are commonly stored in impoundments, surrounded by embankment dams. The demands from the society are constantly increasing regarding the quality and safety of dams. LÄS MER

  5. 4. Soil factors affecting plant performance of climbing beans (Phaseolus vulgaris L.) in south western Kenya

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna Williams; [2016]
    Nyckelord :penetrometer; resistance; soil pH; staking; CN ratio; Kisii; KALRO;

    Sammanfattning : The south west part of Kenya is the most densely populated part of Kenya. This part of Kenya has relatively fertile soils and a favorable environment for crop production, which is why it is a major food producing area. The high population results in land scarcity with the average farm size ranging from 0.8-1. 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
