  1. 1. The effect of taper on pile shaft bearing capacity : Finite element analysis of a tapered wooden pile in sulfate soil

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

    Författare :Jonathan Lindström; [2023]
    Nyckelord :Pile; taper; timber piles; wooden piles; sulphide soil; sulfate soil; tapered piles;

    Sammanfattning : he usage of piles, especially wooden piles, have been going on for thousands of years in construction and foundation reinforcements. Sometimes this was done temporary like the Romans who used wooden piles to construct bridges in Britain, or more permanently like the piles upon which the floating city of Venice stands. LÄS MER

  3. 2. Finite Element Modeling of Installation Effects of Soil-Cement Columns

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

    Författare :Anne Holtmeier; [2022]
    Nyckelord :Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

    Sammanfattning : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. LÄS MER

    Nyckelord :ground vibration; high speed railway; ground vibration boom; critical train speed; VibTrain; Ledsg˚ard; Ostl¨anken; J¨arnasl¨atten. iii;

    Sammanfattning : Trafikverket, the Swedish Transport Administration, has been commissioned by the Swedishgovernment to make plans for new railway mainlines between the country’s three largest cities:Stockholm and Gothenburg/Malm¨o. The planned operating speed of the new mainlines isbetween 250–320 km/h. LÄS MER

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

    Master-uppsats, KTH/Jord- och bergmekanik

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

    Sammanfattning : 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. LÄS MER
