2. Choice of grouting method for jointed hard rock based on sealing time predictions
Sammanfattning : This thesis concerns subjects related to the choice of agrouting method in a jointed hard rock mass. By calculating thetotal sealing time to reach the requested sealing level,different grouting methods could be compared and the mostfavourable chosen. LÄS MER
3. 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
4. Design approaches for grouting of rock fractures; Theory and practice
Sammanfattning : Currently, cement base grout is used widely for sealing of the rock fractures in order to decrease the permeability of rock mass. Grouting procedure is one of the main tasks in cycle of rock excavation. In addition, huge amount of grout should be used during dam construction in order to seal the bedding and embankment walls.
