  1. 1. Slopes in soft clay - management of strength mobilisation

    Författare :Victoria Svahn; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remedial measure; dry crust; climate change; Slope stability; pore water pressure; in situ stress; soft clay; shear strength mobilisation;

    Sammanfattning : Many natural and man-made slopes close to buildings or infrastructure do not demonstrate sufficient levels of safety with respect to their stability. Nonetheless, it is a requirement from society that the environment we live in is safe. LÄS MER

  2. 2. On Rate-Dependency of Gothenburg Clay

    Författare :Mats Olsson; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; K0-triaxial cell; destructuration.; creep; anisotropy; Soft clay;

    Sammanfattning : 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.

  3. 3. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Författare :Anders Kullingsjö; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER

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

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Jorge Yannie; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uplift; soft clay; long-term; installation; tension load; creep rupture; piles; creep of piles; field test; rate dependent; numerical model;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Mats Olsson; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft clay; long-term settlement; creep; test sites;

    Sammanfattning : 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.
