Analysis of water ingress, grouting effort, and pore pressure reduction caused by hard rock tunnels in the Oslo region
Langford, Jenny; Holmøy, Kristin; Hansen, Tom Frode; Holter, Karl Gunnar; Stein, Eivind (Peer reviewed; Journal article, 2022)Many subsurface projects in Scandinavia face challenges with settlement risk from water ingress into tunnels, due to challenging ground conditions featuring hard bedrock underlying soft, marine clay deposits. Pore pressure ... -
Deformation properties of hard rock TBM-spoil
Syversen, Isolde Louise Grønlund (Master thesis, 2021)Bruken av tunnelborremaskiner (TBM) i Norge startet på tidlig 1970-tallet, hovedsakelig knyttet til vannkraftverk. I ettertid har det blitt gravd ut over 250 tunneler i Norge med TBM, store deler knyttet til satsningen på ... -
Effects of Drilling for Tieback Anchors on Surrounding Ground: Results from Field Tests
Lande, Einar John; Karlsrud, Kjell; Langford, Jenny; Nordal, Steinar (Peer reviewed; Journal article, 2020)A full-scale field test program was carried out to investigate the effects of drilling for tieback anchors on the surrounding ground. The test anchors were drilled from the ground surface through a soft clay deposit and ... -
Investigation of Geotechnical Properties of TBM Spoil from the Follo Line Project
Dahl, Marianne (Master thesis, 2018)In connection to the Follo line tunnel project this thesis investigate some of the existing experience on use of TBM spoil as a construction aggregate. Compaction control tests provided by Bane NOR for the deposit at Åsland ... -
Modellering av grunnvannsstrømning i SEEP/W ved tunneldriving
Stølen, Gunhild Viljugrein (Master thesis, 2022)For at et tunnelprosjekt skal være vellykket forutsetter det at ytre miljø ikke blir påvirket i nevneverdig grad av tunneldrivingen. Grunnvann som siver inn i tunnelen kan redusere poretrykket og grunnvannsnivået over store ...
