1. Evaluation of rock mass strength criteria
Abstract : Knowledge of the rock mass behaviour in general, the failure process and the strength in particular, is important for the design of all kinds of underground excavations. One of the most common ways of estimating the rock mass strength is by using a failure criterion. READ MORE

2. Rock mass behavior under hydropower embankment dams with focus on fracture erosion and rock mass stability
Abstract : In Sweden there are about 190 large hydropower dams of varying age. According to the definition by the International Commission of Large Dams (ICOLD), if the height of the dam exceeds 15 m it is referred as large. Majority of these dams are of embankment type. READ MORE

3. Strength, fallouts and numerical modelling of hard rock masses
Abstract : The prediction of compressive stress-induced failures is of concern for the design and construction of deep underground excavations in mining and civil engineering. An overstressed rock mass may result in fallouts of rock, which may cause occupational safety hazards, damage of equipment, and/or production disturbances. READ MORE

4. Scale and Stress Effects on Hydro-Mechanical Properties of Fractured Rock Masses
Abstract : In this thesis, the effects of size and stress on permeability, deformability and strength of fractured rock masses are investigated. A comparison study was carried out to examine the effects of considering, or not considering, the correlation between distributions of fracture apertures and fracture trace lengths on the hydro-mechanical behavior of fractured rocks.

5. Wave propagation in rock and the influence of discontinuities
Abstract : This thesis concerns wave propagation in rock as a tool for determination of rockproperties and as a consequence of activities, such as trains.Using waves as a tool often means that rock properties are determined or the interior of a sample is studied without being damaged. READ MORE
