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

    Författare :Jorge Yannie; Chalmers tekniska högskola; []
    Nyckelord :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;

    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

  2. 2. Beyond the deterministic approach - on the feasibility of data assimilation methods in geotechnics

    Författare :Amardeep Amavasai; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embankment; Uncertainty analysis; Data Assimilation; soft soils;

    Sammanfattning : The surge in economic and social development has resulted in significant challenges, especially for linear physical infrastructure. A substantial part of the ageing physical linear infrastructure has been built on problematic soils and often have poorly documented foundation solutions. LÄS MER

  3. 3. WINDMILL FOUNDATIONS ON WEAK SOILS

    Författare :Wael Mahmoud Mohamed Mohamed; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Much scientific evidence indicates that the Earth's climate is changing and the world has become more concerned about the global climate. This has encouraged many countries to consider future clean power production with wind power taking an increasing part. LÄS MER

  4. 4. Laboratory soft x-ray microscopy and tomography

    Författare :Michael Bertilson; Hans Hertz; Gerd Schneider; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; Diffractive optics; Zone plates; X-ray microscopy; Soft X-ray physics; Tomography; Optics; Optik; Physics; Fysik;

    Sammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER

  5. 5. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders

    Författare :Mirja Rothhämel; Jan Laue; Sven Knutsson; Craig Lake; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft soil; clay; silt; silty sand; soil stabilisation; hydraulic binder; cement; lime; by-product; cement kiln dust CKD ; cold climate; frost; freeze-thaw; laboratory test; field test; subsoil; road construction; feinkörninge Böden; Ton; Schluff; schluffiger Sand; Bodenstabilisierung; hydraulische Bindemittel; Zement; Kalk; Nebenprodukt; Zementofenstaub; kaltes Klima; Frost; Frost-Tau; Laborversuche; Feldversuche; Verkehrsbau; Dauerhaftigkeit; finkornig jord; lera; silt; siltig sand; jordstabilisering; hydraulisk bindemedel; cement; kalk; biprodukt; cement kiln dust CKD ; kallt klimat; frost; frysning-tining; laboratorieanalyser; fältförsök; vägterrass; Geoteknik; Soil Mechanics;

    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
