  2. 1. Modeling aspects of reliability-based design of lined rock caverns

    Author : Davi Rodrigues Damasceno; Fredrik Johansson; Johan Spross; Rafael Jimenez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lined rock cavern; reliability-based design; analytical modeling; finite element modeling; underground gas storage; Inklädda bergrum; tillförlitlighetsbaserad design; analytisk modellering; finita elementmodellering; underjordisk gaslagring; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : The storage of large quantities of hydrogen gas in underground lined rock caverns (LRCs) could contribute to an efficient supply of fossil-free energy. The consequences of failure of such storage can be catastrophic, so representative predictive models and a small probability of failure are needed for the LRC design. READ MORE

    Author : Abbas Zangeneh Kamali; Costin Pacoste; Raid Karoumi; Andreas Andersson; Pedro Galvín; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway bridge dynamics; Soil-structure interaction; Resonance; Analytical solution; Non-proportional damping; Complex mode; Field measurements; FE Model updating; Järnvägsbrodynamik; Jord-bro interaktion; Resonans; Analytisk lösning; Icke-proportionell dämpning; Komplex mod; Fältmätningar; FE Modelluppdatering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The work reported in this thesis presents a general overview of the resonant response of high-speed railway bridges considering soil-structure interaction. The study aims to identify the effect of the surrounding and underlying soil on the global stiffness and damping of the structural system. READ MORE

  5. 3. Tailings Dam Performance : Modeling and Safety Analysis of a Tailings dam

    Author : Roger Knutsson; Annika Bjelkevik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Storage and management of mine waste are both needed in the mining industry. After mineral extraction of the ore, there are generally leftovers with insufficient economical value that need to be taken care of. The finest grained fractions are referred to as tailings. READ MORE

  6. 4. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Author : Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. READ MORE

  7. 5. Modeling of frost heave and surface temperatures in roads

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

    Abstract : Temperature and moisture are very essential parameters when describing the condition of a pavement. In most cases, a high moisture content involves a decreased bearing capacity and, consequently, a shorter durability of the pavement. A frozen pavement has a greater bearing capacity than the corresponding construction in spring or late autumn. READ MORE
