  1. 16. Preconsolidation Pressure of Soft, High-plastic Clays

    Författare :Göran Sällfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the early days only the ground that was best from a geotechnical point of view was used for foundations, but now, owing to the growth of cities and to the rising prices of land, softer and more compressible soils, less suitable for foundations, are also often used.The choice of foundation method is both economically and techni­cally an important matter, and thorough testing of the soil is often needed to determine its geotechnical properties, and thus, to furnish necessary information.

  3. 17. Glass Transition Dynamics in Soft Condensed Matter

    Författare :Johan Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer films; beta relaxation; hydrogen bond; glass transition; polymer dynamics; cooperativity; confinement; IXS; Brillouin light scattering; excess wing;

    Sammanfattning : Materials of very different character, ranging from polymers to metals can be made into glasses. The structural and dynamical properties of glass-forming materials are fundamentally different from those found in crystals. Hence, glassy materials exhibit unique characteristics, which make them suitable for a wide range of applications. LÄS MER

  4. 18. On cyclic accumulation models for degradation of railway foundations

    Författare :Hossein Tahershamsi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural soft clay; Global Sensitivity Analysis; Sobol method; Experimental design; Rate-dependent models; Cyclic accumulation models; Cyclic degradation; Uncertainty analysis;

    Sammanfattning : The degradation of railway foundations due to the repeated loading of traffic induces maintenance and safety obligations for the track operator. One major contributor to track degradation is the accelerated settlement rates in soft soils below the track that lead to alignment issues, especially at stiffness transitions. LÄS MER

  5. 19. Deformation Behavior of Lime/Cement Column Stabilized Clay

    Författare :Sadek Baker; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Deep stabilization of clay with lime/cement columns has lately become one of the most frequent methods for improvement of soft clays. The method is cost effective, as it results in a drastic reduction of settlement. The theories used for design were originally developed for lime columns. LÄS MER

  7. 20. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay

    Författare :Freddie Theland; Jean-Marc Battini; Amir Kaynia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Pile group; End-bearing piles; Dynamic impedance; Environmental vibration; Experimental validation; Dynamisk jord-struktur-interaktion; Pålgrupp; Spetsbärande pålar; Dynamisk impedans; Omgivningsvibrationer; Experimentell validering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. LÄS MER
