Main aspects of deformation and rock support in Norwegian road tunnels
(Journal article; Peer reviewed, 2019)The general geology of Norway makes most of its tunnels to be constructed mainly in strong rock intersected by weakness zones of different sizes and characteristics. The Norwegian support tradition is, to the largest degree ... -
Mangekanters bevegelse på skråplan
(NGI-rapport;58500-04, Research report, 1988-09-22)NGI har en nasjonal forpliktelse til å drive forskning og rådgivningsarbeid innenfor fagfeltet skred. Aktuelle skredtyper er kvikkleireskred, andre løsmasseskred, snøskred og steinskred. Dette forskningsprosjektet berører ... -
Mapping tsunami impacts on land cover and related ecosystem service supply in Phang Nga, Thailand
(Journal article, 2013)The 2004 Indian Ocean tsunami caused damages to coastal ecosystems and thus affected the livelihoods of the coastal communities who depend on services provided by these ecosystems. The paper presents a case study on ... -
Marine monitoring for offshore geological carbon storage—a review of strategies, technologies and trends

Mathematical modeling of dense avalanches
(NGI Publication;203, Chapter, 1998)The paper presents a brief overview of mathematical models for dense avalanches that were developed by researchers of Moscow State University. Examples of calculations for real avalanches in Caucasus and Khibiny Mountains ... -
Maximum frontal speeds, alpha angles and deposit volumes of flowing snow avalanches
(Peer reviewed; Journal article, 2018)Approximate maximum frontal speeds from 89 snow avalanches were analyzed to yield probabilistic estimates of maximum speed scaled with path length parameters. In addition to speeds, 88 companion values of runout for the ... -
Måleresultater etter fullskala sprengningsforsøk – hvor kraftige vibrasjoner tåler en bygning før det oppstår skader
(Conference object, 2019)Grenseverdier for sprengningsvibrasjoner fastsettes på grunnlag av NS 8141 Vibrasjoner og støt. Bergsprengning kan gi så kraftige vibrasjoner at det forårsaker skader på tilstøtende byggverk. Det er imidlertid sjelden at ... -
Måling av injeksjonsresultat med vanntapsmålinger i tunnel
(NGI-rapport;20200436-05-R, Research report, 2022-12-23)Forsøk ved Fornebubanens hovedtunnel har demonstrert at vanntapsmålinger ved stuff kan gjøres enkelt og effektivt, med bruk av lett utstyr. Vanntapsmålingene viser lavt vanntap og meget tett bergmasse etter 2-stegs injeksjon ... -
Måling av krefter på skredoverbygg
(NGI-rapport;75413 Notat 1975-09-01, Research report, 1975-09-01)Design loads on avalanche galleries are of great importance to know and unfortunately they can be extremely variable depending on conditions. In addition, values are difficult to determine and results of present experimental ... -
Measurement of avalanche speeds and forces: instrumentation and preliminary results of the Ryggfonn project.
(Journal article, 1985)The Ryggfonn project is a Full scale experiment carried out to investigate the impact of avalanches on structures and the effects of a retaining dam in the avalanche path. The vertical drop of the avalanche path is 910 m ... -
Metagenomics in CO2 Monitoring
(Journal article, 2013)Leakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying ... -
The meteorological condition for larger avalanches at Senjojiki Bowl in Japanese Central Alps
(NGI Publication;203, Chapter, 1998)The Senjojiki Bowl has a typical avalanche terrain consisting of8 avalanche tracks. During the last 25 years 16 alpinists and ropeway workers in total have been killed by avalanches. Since no reliable avalanche warning is ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
Microplastic in sediments and fauna. Offshore and inshore
(NGI Rapport;20210130-01-R, Report, 2022-01-31)Samples of sediment and sediment-dwelling organisms were obtained from the Norwegian Continental Shelf and fjords in Southern Norway. These are referred to as offshore areas and inshore areas, respectively. The sediments ... -
Microseismic monitoring and interpretation of injection data from the In Salah CO2 storage site (Krechba), Algeria
(Journal article, 2013)Microseismic data analysis together with interpretation of injection data at the In Salah CO2 storage site provides a valuable tool for improved understanding of the subsurface injection and storage processes. More than ... -
