1. The effect of scale on the morphology, mechanics and transmissivity of single rock fractures
Abstract : This thesis investigates the effect of scale on themorphology, mechanics and transmissivity of single rockfractures using both laboratory and in-situ experiments, aswell as numerical simulations. Using a laboratory 3D laserscanner, the surface topography of a large silicon-rubberfracture replica of size 1m x 1m, as well as the topography ofboth surfaces of several high-strength concrete fracturereplicas varying in size from 50mmx50mm to 200mm x 200mm, werescanned.

2. Numerical modelling of jointed rock masses by distinct element method for two- and three-dimensional problems
Abstract : The mechanical behaviour of a jointed rock mass is strongly, and sometimes dramatically, affected by the behaviour of the discontinuities present in jointed rock mass. In many cases, preferential failures are dominated or defined by the natural discontinuities present in the neighborhood of engineering engineering works. READ MORE
