    Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER

  2. 2. Identification of soil parameters in an embankment dam by mathematical optimization

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Pooya Vahdati; Luleå tekniska universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The finite element method (FEM) has been widely used to analyse earth and rockfill dams. In a finite element analysis a proper constitutive model has to be chosen for each part of the dam in order to simulate the relation between stresses and strains. The zones of an earth and rockfill dam have different functions. LÄS MER

  3. 3. Stability of tailings dams focus on numerical modelling

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Muhammad Auchar Zardari; Luleå tekniska universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Upstream tailings dams may experience slope stability problems when the rate of raising is too fast. Tailings consolidate slowly due to low hydraulic conductivity. The excess pore pressures can build up due to accelerated rate of raising. LÄS MER

  4. 4. On Parameter Identification for Better Predictions of Dam Behaviour

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Jasmina Toromanovic; Luleå tekniska universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : 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. LÄS MER
