  1. 11. Hydrogeological Methods in Geotechnical Engineering: Applied to settlements caused by underground construction

    Författare :Jenny Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; excavation; tunnel; hydrogeology; consolidation; pumping test; Groundwater; inflow rate; settlement; transmissivity; pore pressure; clay;

    Sammanfattning : Improvement in the infrastructure in urban areas generally involves underground construction with tunneling and deep excavations. One important consideration when constructing in cities founded on soft soil is settlement resulting from groundwater drawdown. The potential cost of excessive settlement in these projects is immense. LÄS MER

  3. 12. A study on emerging electronics for systems accepting soft errors

    Författare :Joakim Alvbrant; J. Jacob Wikner; Emil Nilsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic clay; Redundant systems; Memristor; Wireless sensor networks;

    Sammanfattning : Moore’s law has until today mostly relied on shrinkage of the size of the devices inintegrated circuits. However, soon the granularity of the atoms will set a limit together with increased error probability of the devices. How can Moore’s law continue in thefuture? To overcome the increased error rate, we need to introduce redundancy. LÄS MER

  4. 13. On the small strain stiffness of some Scandinavian clays and impact on deep excavation

    Författare :Tara Wood; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; small strain stiffness; degradation; seismic testing; sample quality;

    Sammanfattning : This thesis presents the results of a comprehensive study on the small strain stiffness of several Swedish clays and its tentative effect on the design of retaining structures. A combination of field measurement techniques, seismic dilatometer and surface seismics, are complemented with bender element testing of the retrieved samples. LÄS MER

  5. 14. In-situ testing of floating thermal piles in soft sensitive clay

    Författare :Anders Bergström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

    Sammanfattning : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. LÄS MER

  7. 15. Multidisciplinary Near-Surface Investigation of a Quick-Clay Landslide Prone Area in Southwest Sweden

    Författare :Silvia Salas Romero; Alireza Malehmir; Ian Snowball; Christopher Juhlin; Laura Valentina Socco; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quick-clay; reflection seismic; landslide; southwest Sweden; borehole logging; physico-chemical properties; hydrogeological modelling; multichannel analysis of surface waves; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Quick-clay landslides are considered one of the most important geohazards in Sweden, Norway, and Canada. The deposits involved are glacial and postglacial clays and silty clays, which are very sensitive to increased stress that may collapse their structure and cause liquefaction. LÄS MER
