  2. 1. 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.

  4. 2. 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.

  5. 3. 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

  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. The Unloading Modulus of Soft Soil: A Field and Laboratory Study

    Author : Jenny Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; heave; Clay; case study; excavation;

    Abstract : Improved infrastructure in urban areas often necessitates underground construction, where the unloading behaviour of the soil is of importance for predicting the amount of heave and how long it will take for the soil to swell. It is of particular interest to study the need for the installation of tension piles, as well as whether the tunnel will be subjected to settlement or heave in the long term. READ MORE
