1. 1. The Impact of Fracture Orientation on the Choice of Grout Fan Geometry - a Statistical Analysis

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Fredrik Osterman; [2019]
   Nyckelord :Rock Fissure Grouting; Grout Fan Geometry; Geology; Discrete Fracture Network; Sprickinjektering i berg; skärmgeometri; geologi; diskreta spricknätverk;

   Sammanfattning : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. LÄS MER

3. 2. Comparison of Photogrammetry Interpretation with Physical Structural Field Measurements

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Nyckelord :Fracture mapping; photogrammetry; 3D-modelling; rock classification; field safety; Sprickkartering; fotogrammetri; 3D-modellering; bergklassificering; säkerhet i fält;

   Sammanfattning : Fracture mapping of bedrock and knowledge about how fractures influence rock strength and stability is of great importance in a constructional context. These factors largely dictate where one can build and not build in rock, and to what extent reinforcements and safety measurements are needed. LÄS MER
