1. Bonded Particle Model for Jointed Rock Mass
Sammanfattning : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. LÄS MER
2. Theoretical and numerical study of jointed rock mass behaviour
Sammanfattning : .... LÄS MER
3. Mathematical modelling of jointed rock masses
Sammanfattning : In this thesis, a theoretical model of the mechanical behaviour of jointed rock masses is developed. An equivalent material approach is used to formulate the constitutive equations, where the structural components, intact rock and joints are assigned continuous material properties. LÄS MER
4. Rock Mass Characterisation Using Drill Performance Monitoring : Problems, Analysis challenges and Limitations
Sammanfattning : In open pit mining, it is important to know as much information as possible about rock masses to be mined for more cost-effective mining operation. In rock engineering perspective, information about rock mass characteristics usually includes hardness of the rock, geological features, fractures, faults, ore contacts, water bearing stratum.

5. Rock mass response during high pressure grouting
Sammanfattning : The sealing of hard jointed rock by grouting involves several complicated mechanical systems. The result is a complex coupled system of hydro- logical and mechanical precesses. In order to determine the higher order effects of the resulting system the fracture deformations must be assessed. LÄS MER
