  1. 1. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  3. 2. Exploring the Diversity of Exoplanets

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rebecka Svensson; [2021]
    Keywords : Exoplanets; Super-Earth; Sub-Neptune;

    Abstract : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. READ MORE

  4. 3. Three-dimensional effects in slope stability for shallow excavations : Analyses with the finite element program PLAXIS

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Niclas Lindberg; [2020]
    Keywords : ;

    Abstract : The purpose with this study was to investigate the impact of three-dimensional effects in slope stability for three-dimensional excavations and slopes with cohesive soils and compare the results with the method provided by the Swedish commission of slope stability in 1995 regarding three-dimensional effects. Both the factor of safety and the shape of the slip surface was compared between the methods but also the results from their equivalent two-dimensional geometry. READ MORE

  5. 4. Internal Erosion and Dam Stability : Analysis of the internal erosion effects on stability of an embankment dam

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Arthur Jedenius; [2018]
    Keywords : Internal erosion stability finite element analysis method plaxis slope seep;

    Abstract : Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. READ MORE

  6. 5. Progressive landslide analysis : Applications of a Finite Difference Method by Dr. Stig Bernander Case Study of the North Spur at Muskrat Falls, Labrador, Canada

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Robin Dury; [2017]
    Keywords : Downhill progressive landslides; Slope stability; Sensitive clay; Deformation softening; Finite difference method; Brittle failure in clay; Liquefaction; Muskrat Falls project;

    Abstract : An easy-to-use spreadsheet version of a finite difference method for progressive landslide analysis has been developed. The finite difference method was originally developed by Dr. Stig Bernander, earlier adjunct professor at Luleå University of Technology and head of the Design Department of Skanska AB in Gothenburg, Sweden..
