Simplified computational methods for estimating dynamic impedance of batter pile groups in homogeneous soil
(Peer reviewed; Journal article, 2021) -
Simulating low frequency sound transmission through walls and windows by a two-way coupled fluid structure interaction model
(Peer reviewed; Journal article, 2017)Aircraft, supersonic flights, blasts, and explosions emit sound with substantial energy below 100 Hz. When the low frequency sound is transmitted inside a building, it generates vibration and rattling that may lead to ... -
Simulating run-up on steep slopes with operational Boussinesq models; capabilities, spurious effects and instabilities
(Peer reviewed; Journal article, 2013) -
Simulating tsunami propagation in fjords with long-wave models
(Journal article, 2015)Tsunamis induced by rock slides constitute a severe hazard towards coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the short-frequency and high-amplitude tsunamis in this environment ... -
Simulation of snow-avalanche flow in run-out zones.
(Journal article, 1989)The authors of this paper have previously, in 1987, outlined the development of a set of constitutive equations representing the behaviour of avalanching snow, and the resulting equations for fully developed steady shear ... -
Simulations of dense snow avalanches on deflecting dams
(Journal article, 1998)Two models simulating snow avalanches impacting retaining dams at oblique angles of incidence are presented. First, a lumped-mass model applying the Voellmy-Perla equation is used to calculate the path of the centre-of-mass ... -
Site characterisation and some examples from large scale testing at the Klett quick clay research site
(Peer reviewed; Journal article, 2019)The Klett research site was developed in conjunction with the new E6 developments south of Trondheim, Norway. The site comprises non-sensitive clay to about 6 m to 8 m and quick clay with significant silt lenses below this ... -
Site-specific soil reaction model for monopiles in soft clay based on laboratory element stress-strain curves
(Peer reviewed; Journal article, 2020)Large-diameter monopiles are the predominant foundation solution for supporting offshore wind turbines. They are conventionally designed using soil reaction curves developed for long slender piles used for supporting ... -
Skred og skredfare
(NGI Publikasjon;122, Journal article, 1978)Allerede samme år som NGI offisielt ble opprettet fikk man i oppdrag å undersøke kvikkleireskredet som gikk på Bekkelaget ved Oslo 7. oktober 1953... -
Skred og skredforskning i Norge
(Chapter, 1999)Siden man begynte offentlig registrering over årsak til dødsulykker i 1835, har ca. 1500 mennesker satt livet til i ulykker som skyldes snøskred eller sørpeskred i Norge. I Alpelandene var man også vel vant med den hvite ... -
Skredfare, boligplanlegging og ekspertens rolle overfor oppdragsgiver
(Journal article, 1978)Trange dalfører og bratte fjellsider er svært vanlig i vårt land og i fjord. og dalstrØkene særlig pA Vestlandet og i Nord-Norge er naturødeleggelse i fonn av skred en realitet. I mange dalfører er f.eks. gArdsbebyggelsen ... -
The SLAB test - The missing link in stability testing?
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)An avalanche is released when both the weak layer and the slab fails, still standard stability tests (e.g. CT, ECT) focus on the weak layer only. The SLAB test gives information on both the weak layer and the slab, hence ... -
Slush-flow questionnaire.
(Journal article, 1989)Questionnaires concerning slush flows were distributed globally. The purpose of the questionnaire was to determine the geographic distribution of slush-flow activity and also to collect information concerning the most ... -
Slushflow Formation, Flow Regimes and Consequences (Short Version)
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)The term ‘slushflow’ was introduced by Washburn and Goldthwait (1958). Eight people perished in slushflows during the winters 2010 and 2011 in Norway, five in backcountry, two in their home and one truck-driver. Buildings, ... -
Slushflow hazard - where, why and when? 25 years of experience with slushflow consulting and research.
(Journal article, 1998)Slushflows — flowing mixtures of water and snow — are a major natural hazard in Norway. Knowledge gathered by the Norwegian Geotechnical Institute during 25 years of slushflow consulting and research is presented. The ... -
Slushflow hazard control. A review of mitigative measures.
(NGI Publication;203, Chapter, 1998)Slushflow hazard detection and control are based on both active and passive mitigative measures performed above and within the starting zones as well as along the path and in the runout zone. The main aim of preventive ... -
Slushflow hazard prediction and warning
(Journal article, 2004)Parameters critical to slushflow release have been studied during 11 winters in Rana, North Norway. Slushflows occurred during 16 periods within the research areas and during another 13 in the district. A noticeable rise ... -
Slushflows: Basic properties and spreading
(NGI Publication;203, Chapter, 1998)The article presents results of an analytical review of factual data and scientific studies concerning slushflows. The basic conditions and gears of origin, parameters and typology of flows are considered, as well as the ... -
Small strain stiffness within logarithmic contractancy model for structured anisotropic clay
(Peer reviewed; Journal article, 2021)Stiffness of soils in the small strain region is high and it decays nonlinearly with increasing shear strains or with mobilization of shear stresses. However, the commonly used critical state based constitutive models use ...
