  1. 1. Aspects on probabilistic approach to design : From uncertainties in pre-investigation to final design

    Författare :Anders Prästings; Stefan Larsson; Rasmus Müller; Jan Laue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design; Geotechnical design; Geotechnical structures; Sheet-pile wall; Characterization of uncertainties; Geotechnical investigations;

    Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Exploring a medium (soil) that is almost entirely and completely hidden from us is no easy task. Investigations can be made only at discrete points, and the majority of a specific soil volume is never tested. LÄS MER

  3. 2. Managing uncertainties in geotechnical parameters : From the perspective of Eurocode 7

    Författare :Anders Prästings; Stefan Larsson; Johan Spross; Rasmus Müller; Kok-Kwang Phoon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eurocode 7; Characteristic value; Partial-factor method; Reliability-based design; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Geotechnical site investigations are made only at discrete points and most of a soil volume is never tested. A major issue is therefore how to cost effectively reduce geotechnical uncertainties with respect to structural performance. LÄS MER

  4. 3. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations

    Författare :Roger Wisén; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; Hydrogeology; geographical and geological engineering; resistivity method; surface wave seismic method; inverse modelling; site investigation; geophysics;

    Sammanfattning : The adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. LÄS MER

  5. 4. Value of Information Analysis in Rock Engineering Investigations

    Författare :Miriam Zetterlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Observational Method; Rock mass characterisation; Value of Information;

    Sammanfattning : A challenge in rock engineering is to strike a balance between a reasonable level of investigation and uncertainty in the geological conditions. Value of Information Analysis (VOIA) provides support for decisions about investigation strategies. LÄS MER

  7. 5. Laboratory Investigations of Frost Action Mechanisms in Soils

    Författare :Deniz Dagli; Jan Laue; Tommy Edeskär; Lukas Arenson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold Regions Soil Mechanics; Frost Action; Frost Depth; Frost Heave; Heat Flow in Soils; Ice Lens Formation; Image Analysis; Laboratory Freezing Test; Soil Mechanics; Geoteknik;

    Sammanfattning : Phase change of the water in the soil skeleton under cold climate conditions (also known as frost action in soils) affects soil properties and can be responsible for serious alterations in a soil body; causing damages (due to the volumetric expansion known as frost heave) to structures on or below the ground surface such as foundations, roads, railways, retaining walls and pipelines, etc. In order to improve the current design methods for roads against frost action, the Swedish Transport Administration (Trafikverket) has initiated a research program.
