1. Modeling flow and transport in fractured rock : role of heterogeneity, support scale and transport channeling
Abstract : .... READ MORE

2. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting
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. Solute transport in fractured rocks : Analysis of analytical solutions and determination of transport parameters
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. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces
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. Fractured Rock Masses as Equivalent Continua - A Numerical Study
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.
