    Keywords : fractured rock; modeling; heterogeneity; stochastic models; scale;

    Abstract : .... READ MORE

  2. 2. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting

    Author : Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Philipp Hartlieb; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement while drilling; Photogrammetry; Rock fragmentation; Gruv- och berganläggningsteknik; Mining and Rock Engineering;

    Abstract : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. READ MORE

  3. 3. Solute transport in fractured rocks : Analysis of analytical solutions and determination of transport parameters

    Author : Shuo Meng; Longcheng Liu; Ivars Neretnieks; Lanru Jing; Klaus-Peter Kröhn; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Fractured rock; Radionuclide transport; Analytical solution; Dispersion mechanisms; Electromigration.; Sprickigt berg; Radionukidtransport; analytisk lösning; Dispersionsmekanismer; Elektromigration.; Chemical Engineering; Kemiteknik;

    Abstract : In order to facilitate the assessment of the safety and function of deep geological repositories for radioactive waste, several models have been developed to describe water flow and transport of solutes in fractured crystalline rock. The rock around the repository is described and modelled as a network of water-bearing fractures. READ MORE

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

    Author : Quanhong Feng; KTH; []
    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

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

    Author : Ki-Bok Min; KTH; []
    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.
