An anisotropic elastoplastic model for soft clays based on logarithmic contractancy
(Journal article, 2015)A new constitutive model for soft structured clays is developed based on an existing model called S-CLAY1S, which is a Cam clay type model that accounts for anisotropy and destructuration. The new model (E-SCLAY1S) uses ... -
An anisotropic shear strength model for cyclic accumulated plastic strain of overconsolidated clay
(Journal article, 2014)Many geotechnical problems involve calculation of the permanent deformation of overconsolidated clay under undrained cyclic loading. There are many existing methods in the literature which have been made for predicting ... -
An Evaluation of the Applicability of Current Ground-Motion Models to the South and Central American Subduction Zones
(Journal article; Peer reviewed, 2012)The applicability of existing ground‐motion prediction equations (GMPEs) for subduction‐zone earthquakes is an important issue to address in the assessment of the seismic hazard affecting the Peru–Chile and Central American ... -
Analyse av værforhold ved utvalgte skredsituasjoner i Ørsta
(NGI-rapport;58308-22, Research report, 1981-03-17)The meteorological phenomena of avalanches in Nivane, ørsta, Norway, for the period from 1960 to 1980 and for the years 1941 and 1942 have been analysed. We have analysed the meteorological phenomena of some situations ... -
Analysis of an artificially triggered avalanche at the nepheline syenite mine on Stjernøya, Alta, Northern Norway
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)Since 1961, a Nepheline Syenite mine is operated on the island of Stjernøya in the Altafjord, Northern Norway. The facilities are located in Lillebukt, on the southern side of the island. Above the facilities, the Nabbaren ... -
Analysis of avalanche measurements out of the runout area of NGI's full-scale test-site Ryggfonn
(Journal article, 2009)The paper summarizes measurements and observations of dry-snow avalanches at the Ryggfonn test-site with respect to their behavior in the runout area. Measurements of front velocities and retarding accelerations are presented ... -
Analysis of water ingress, grouting effort, and pore pressure reduction caused by hard rock tunnels in the Oslo region

Analytical solution for tunnelling-induced response of an overlying pipeline considering gap formation
(Peer reviewed; Journal article, 2023)Soil-pipeline separation due to tunnelling has been certainly substantiated in previous model tests. However, this phenomenon has seldom been considered in current analytical solutions. This study formulates a tensionless ... -

Annual Report 2018 [SP 4 FoU Snøskred]
(NGI-rapport;20170131-11-R, Research report, 2018-12-21)In the second year of the present three-year project period, core and/or long-term activities were continued: -experiments at Ryggfonn and maintenance of the site, -infrasound monitoring along State Road 15 between Fonnbu ... -
Annual Report 2019 [SP4 FoU Snøskred]
(NGI-rapport;20170131-17-R, Research report, 2020-05-28)NGI has conducted research on avalanches and related processes since 1973. This report gives a short insight in the work done in 2019. While experiments with artificial release of avalanches in the Ryggfonn experimental ... -

Antarctic-wide array of high-resolution ice core records reveals pervasive lead pollution began in 1889 and persists today
(Journal article, 2014)Interior Antarctica is among the most remote places on Earth and was thought to be beyond the reach of human impacts when Amundsen and Scott raced to the South Pole in 1911. Here we show detailed measurements from an ... -
Anthropogenic impact on marine ecosystem health: A comparative multi-proxy investigation of recent sediments in coastal waters
(Journal article; Peer reviewed, 2018)Hazardous substances entering the sea, and ultimately deposited in bottom sediments, pose a growing threat to marine ecosystems. The present study characterized two coastal areas exposed to significant anthropogenic impact ... -
Anvendelse av risikoanalyse i skredfarevurderingen
(Chapter, 1979)Trange dalfører og bratte fjellsider er svært vanlig i vart land og i fjord~ og dalstrøkene,særlig pa Vestlandet og i Nord-Norge er naturødeleggelse i form av skred en realitet. I mange dalfører er f.eks gärdsbebyggelsen ... -
APALI – Avalanche Probability Along Linear Infrastructure
(NGI-Rapport;20200431‐01‐TN, Research report, 2023-09-28)To secure linear infrastructure in the most cost-efficient manner, hazard hot-spots need to be known not only with regard to the intensity of possible events but also their probability. Traditional hazard mapping methods ...
