  2. 1. Calculating long-term settlement in soft clays - with special focus on the Gothenburg region

    Author : Mats Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft clay; long-term settlement; creep; test sites;

    Abstract : Long-term settlement in clay constitutes an engineering challenge in road design and construction in areas with deep deposits of soft clay. Soil improvement and construction of building foundations or embankments can be quite complicated and expensive in such areas. Construction costs need to be balanced against high maintenance costs.

  4. 2. On Probability in Geotechnics. Random Calculation Models Exemplified on Slope Stability Analysis and Ground-Superstructure Interaction

    Author : Claes Alén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; random; creep; slope stability; calculation; interaction; design; limit state; probability; statistics; geotechnics;

    Abstract : The thesis deals with uncertainty in calculation modelling. Emphasis is put on the design state. Design is a chain of decisions under uncertainty. A probabilistic approach is used to describe the uncertainty and calculations as a way to reveal the uncertainty. READ MORE

  5. 3. Long Term Settlements in Soft Clays

    Author : Peter Claesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calculation model; settlements; stress-strain-strain rate; consolidation; deep layers; case records; creep; lightly overconsolidated soft clay;

    Abstract : When structures are founded on deep layers of lightly overconsolidated, soft clay large settlement often occur during a long period of time after completion of the structure. Therefore it is of major importance to be able to calculate and predict the expected settlements with a satisfactory degree of accuracy, as this has a great impact on the design of the foundation and the possible need for soil improvements.

  6. 4. On Rate-Dependency of Gothenburg Clay

    Author : Mats Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; K0-triaxial cell; destructuration.; creep; anisotropy; Soft clay;

    Abstract : On Rate-Dependency of Gothenburg ClayMATS OLSSONDepartment of Civil and Environmental EngineeringDivision of GeoEngineeringChalmers University of TechnologyABSTRACTLong-term settlements in clay constitute a major engineering challenge in areas with deep deposits of soft clay. This dissertation aims to extend the understanding and theoretical framework of rate-dependent soil behaviour, so that uncertainties in predictions of long-term settlements are significantly reduced.

  7. 5. 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
