  2. 1. On the long-term behaviour of tension loaded piles in natural soft soils

    Author : Jorge Yannie; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

    Abstract : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. READ MORE

  4. 2. In-situ testing of floating thermal piles in soft sensitive clay

    Author : Anders Bergström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

    Abstract : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. READ MORE

  5. 3. Behaviour of Piles with Enlarged Tip in Non-Cohesive Soil. Model Tests and Numerical Simulations

    Author : Torbjörn Edstam; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerical simulations; plasticity; model tests; enlarged tip; piles; large strains; sand;

    Abstract : Slender piles reduce detrimental vibrations during installation. In order to preserve a high bearing capacity, the pile tip can be enlarged after installation. This study consists of model tests of conventional piles (unexpanded piles) and piles with enlarged tip (expanded piles). READ MORE

  6. 4. Design of steel piles for integral abutment bridges

    Author : Hans Petursson; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integral abutment bridges; steel piles; jointless bridges; Steel Structures; Stålbyggnad;

    Abstract : In 1999 research was started at Luleå University of Technology with the purpose to collect experiences from USA and UK on bridges with integral abutments and transfer the experience to Swedish conditions. Since then at least 20 integral bridges with one row of piles under each abutment have been built in Sweden and the European research project INTAB has been completed. READ MORE

  7. 5. Long-term set-up of driven piles in sand

    Author : Gary Axelsson; KTH; []
    Keywords : driven piles; shaft capacity; instrumentation; sand; set-up; torque; loading tests; soil ageing; time effects; driven rods; dynamic probing;
