  2. 21. On Parameter Identification for Better Predictions of Dam Behaviour

    Author : Jasmina Toromanovic; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Numerical modelling is often needed as a tool to predict the behaviour and assess the safety of dam structures. Embankment dam structures analyses are quite complex and potential failures are hazardous. Predictions of dam behaviour by numerical modelling rely on knowledge about the mechanical properties of the materials the dam is constructed with. READ MORE

  4. 22. A Critical Review of the Observational Method

    Author : Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. READ MORE

  5. 23. Numerical analyses of stability of a gradually raised tailings dam

    Author : Muhammad Auchar Zardari; Daichao Sheng; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tailings dams; consolidation; rockfill berms; slope stability; corner; internal erosion; finite element analysis; Soil Mechanics; Geoteknik;

    Abstract : Numerical analyses are presented in this thesis to address potential stability problems that may occur during gradual raisings and under seismic loading conditions of Aitik tailings dam in northern Sweden. The dam is mainly raised using upstream construction method. It is planned to raise the dam gradually in several stages. READ MORE

  6. 24. Outdoor Mobility, Place and Older People - Everyday Mobilities in later Life in a Swedish Neighbourhood

    Author : Vanessa Stjernborg; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motility; Social participation; Social sustainability; Suburb; Transition; Urban fear; Wellbeing;

    Abstract : The overall aim of this thesis is to offer an understanding of everyday mobilities outdoors among older persons from a place- and context-dependent perspective. The emphasis is to take a gentle approach towards an overall perspective with consideration to physical aspects (like the home neighbourhood), social aspects (like social networks and social participation) and mental aspects (like place images, mental maps and fear of crime).

  7. 25. On the Assessment of Internal Erosion of Dam Cores of Glacial Till

    Author : Hans Rönnqvist; Kaare Höeg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The objective of this study is twofold; on the one hand it investigates the susceptibility to suffusion of glacial till, and, on the other, it presents approaches to evaluate internal erosion susceptibility of dams composed of this type of core soil. Concentrated leak erosion, backward erosion, contact erosion, and suffusion erosion are the mechanisms associated with the initiation of internal erosion. READ MORE
