WP 2 – Full-scale experiments at Ryggfonn Ryggfonn avalanche observations 2020/2021
(NGI-rapport;20200017-06-TN, Research report, 2022-04-07)NGI continues to operate the avalanche test site at Ryggfonn in Stryn municipality, Vestland county, western Norway (61.969°N, 7.275°E). In addition to the field work and data collection performed in the context of WP2 – ... -
WP1 - Container experiments - Yearly report 2021
(NGI-rapport;20200436-09-R, Research report, 2023-05-08)Container experiments investigating leaching from alum shale under different conditions were started autumn 2020 as a part of the Under Oslo project at NGI (SP13). Furthermore, leaching from alum shale mixed with different ... -
WP1 - Mixed fractions of black shale and rhomb porphyry
(NGI-rapport;20200436-02-R, Research report, 2023-02-20)When taking out potentially acid-producing black shale in construction projects, rock masses are often unintentionally mixed with masses of other rocks. The acid-producing potential of such mixed masses is uncertain, and ... -
WP1 - Rhomb porphyry - data report
(NGI-rapport;20200436-08-R, Research report, 2021-12-22)Samples of rhomb porphyry have been characterized with chemical analyses and different leaching experiments (column, container and standard leaching tests) to study their composition and leaching properties. Results ... -
WP1 - Temporary storage of black shales – a compilation of case studies, experiences and overall conclusions
(NGI-rapport;20200436-03-R, Research report, 2023-01-09)As a part of the internal R&D project "Under Oslo" at NGI, several aspects of temporary storage of black shale has been investigated. Information from different experiments and cases of black shale storage from the ... -
Yield Stresses in Soft Contracting Clays
(NGI Publication;209, Chapter, 2022)The undrained shear strength su along an arbitrary failure plane can be expressed as: su = 1/2(σ'ULS − σ'LLS) (1) where σ'ULS and σ'LLS denote the upper (U) and lower (L) effective, normal, compressive failure stresses ... -
Årsrapport [FoU Snøskred 2012]
(NGI-rapport;20120031-01-R, Research report, 2013-02-01)Rapporten beskriver aktivitetene som er gjennomført i 2012 innenfor FoU prosjektet ”Snøskred” finansiert gjennom NVE. Prosjektet er delt inn i 4 hovedområder: - Modellering - Varsling - Sikringstiltak, herunder ... -
Økt skredfare kan avverges
(Klima;1-2009, Chapter, 2009)Klimaendringer gir villere vær, mer nedbør og flere skredhendelser i deler av Norge. Men dette trenger ikke føre til flere dødsfall og økte materielle skader, hvis vi bruker sunn fornuft og følger bygningsloven. -
