This one-day short course will cover some key elements of the lecturers’ developments and work in rock mechanics, rock engineering and structural geology, respectively. The course will start with a structural geology lecture. A brief reminder is given of some fundamentals: stress, brittle failure and the factors that determine joint or fracture spacing, regularity and continuity within a set, in other words important parts of our input geometries for rock mechanics, modelling, and empiricism. The non-linear shear strength of rock, rock joints and rock masses will be covered next, as these are fundamental to many areas of rock engineering and needed for input to realistic numerical UDEC-BB and 3DEC (jointed) modelling. The second structural geology lecture will be about the the geometry of the joint or fracture network and its influence on rock mass bulk properties, such as connectivity, conductivity and strength. Fundamentals of rock mass anisotropy will follow, including the quantification of deformability, seismic velocity and permeability, to contrast with today’s commonly applied isotropic modelling. The last two lectures will be empirically based, and mostly concern rock engineering in tunnelling. The Q-system is an example of observational empiricism, using rock mass classification as a basis for site-interpretation and tunnel-and-cavern design assistance, including input for numerical modelling. TBM tunnelling performance will follow, from world records to more common performance, especially the surprises, problems and big delays sometimes caused by fault zones. The QTBM prognosis method for estimating penetration rate PR and actual advance rate AR, will be described, applied and illustrated.
