6. Rock support in weak rock : a study on the URI project
Sammanfattning : .... LÄS MER
7. Terrain navigation for underwater vehicles
Sammanfattning : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. LÄS MER
8. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces
Sammanfattning : 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. LÄS MER

10. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring
Sammanfattning : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. LÄS MER
