  2. 2. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces

    University dissertation from Institutionen för anläggning och miljö

    Author : Quanhong Feng; KTH.; [2001]
    Keywords : 3-D laser scanner; close-range photogrammetry; engineering geology; fracture geometry; fracture mapping; rock engineering; rock faces; rock mechanics; three-dimension; total station;

    Abstract : To analyse the influence of fractures on hydraulic andmechanical behaviour of fractured rock masses, it is essentialto characterise fracture geometry at exposed rock faces. Thisthesis describes three semi-automatic methods for measuring andquantifying geometrical parameters of fractures, and aims tooffer a novel approach to the traditional mapping methods. READ MORE

  3. 3. Fractured Rock Masses as Equivalent Continua - A Numerical Study

    University dissertation from Stockholm : Mark och vatten

    Author : Ki-Bok Min; KTH.; [2004]
    Keywords : fractured rock masses; equivalent continuum; discrete fracture Network DFN ; Distinct Element Method DEM ; Finite Element Method FEM ; Nuclear Waste Disposal; Coupled Thermo-Hydro-Mechanical Processes;

    Abstract : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.

  4. 4. Heterogeneity-Induced Channelling, Flow-Wetted Surface, and Modelling of Transport in Fractured Rock

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Larsson; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; channelling; flow-wetted surface; fractured rock; solute transport; groundwater modelling; groundwater; Hydrology; Hydrologi;

    Abstract : Heterogeneities in fractured rock are found at all scales; from the scale of individual fractures, to the scale of fracture networks, and to the largest regional scales. These heterogeneities cause challenges for modelling and parameter estimation of flow and solute transport. READ MORE

  5. 5. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

    University dissertation from Stockholm : Department of Physical Geography, Stockholm Univeristy

    Author : Benoît Dessirier; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturgeografi; Physical Geography; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal;

    Abstract : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. READ MORE
