3D FE tool for time dependent settlement predictions
(Chapter, 2016)A newly developed calculation tool for fully coupled general 3D finite element consolidation analyses is presented. The development has been part of an ongoing Research and Development project called GeoFuture and the tool ... -
3D modelisation of snow slabs stability.
(NGI Publication;203, Chapter, 1998)Snow slabs stability is a real problem to study in a mecanical point of view. A non exhaustive review of the different factors used to evaluate this stability or instability is done. All of them have been done in two ... -
A Framework for Versatile Shape of Yield Surfaces for Structured Aniso-tropic Soft Soils
(Chapter, 2016)A framework based on logarithmic contractancy is proposed to produce versatile shapes of yield surfaces for structured anisotropic clays. The recently proposed constitutive model (E-SCLAY1S) is an extension of existing ... -
A Novel Small-Scale Model Testing Device for Laterally Loaded Piles

A procedure for the assessment of the undrained shear strength profile of soft clays
(Chapter, 2016)In the geotechnical research community, there is widespread agreement that the choice of the characteristic undrained shear strength (cuA) is very important and plays an essential role in the design and stability analysis ... -
A thermal profile of coastal permafrost at Varandey, Russia
(Chapter, 2017)Soil temperature variation is one of the governing factors to the stability of soil masses in regions affected by permafrost. Understanding of the thermal profile is critical for planning, designing, constructing and ... -
Acoustic sensor to measure snowdrift and wind velocity for avalanche forecasting
(NGI Publication;203, Chapter, 1998)A new mathematical model of slushflow dynamics is developed. A slushflow is treated as a two-layer flow. The lower layer consists of pure liquid phase (water) and the upper layer is a floating water saturated snow (slush). ... -
All-weather avalanche activity monitoring from space?
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)Information on avalanche activity or on non-activity on local and regional scale is of great value for avalanche warning services, traffic authorities and experts responsible for safety in communities or ski resorts. In ... -
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 ... -
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 ... -
Application of two novel CPTu-based stratification models

Associations between shear strength of a buried surface hoar layer and stratigraphic, topographic and vegetation characteristics on a uniform slope. Extended abstract
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)In this study we quantify 1) changes in spatial and aspatial characteristics of the shear strength of a buried surface hoar layer, and 2) identify characteristics in terrain, vegetation and snow stratigraphy that can help ... -
Automated Avalanche Deposit Mapping From VHR Optical Imagery
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Using eCognition we developed an algorithm to automatically detect and map avalanche deposits in Very High Resolution (VHR) optical remote sensing imagery acquired from satellites and airplanes. The algorithm relies on a ... -
The avalanche at Flateyri, Iceland October 26th 1995 and the avalanche history
(NGI Publication;203, Chapter, 1998)An avalanche struck the village Flateyri on 26.10.1995 killing 20 people. There was also an enormous property damage. The avalanche went further than previously known for avalanches from Skollahvilft. The weather conditions ... -
Avalanche caused catastrophes on the mountainous rivers
(NGI Publication;203, Chapter, 1998)Alongside with the danger of snow avalanching for the objects and population, the subsequent phenomena caused by the avalanching are not less serious. One of such reasons can be the choked lakes and outflash floods on the ... -
Avalanche characterization for regional forecasting
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)In the Sunnmøre and Romsdal road districts in Western Norway, the local road authorities have compiled a register of more than 300 sites where avalanches encounter principal roads in the area. The area covered is about 5 ... -
Avalanche control measures for roads in Norway
(Chapter, 1994)In a mountainous country like Norway the roads are exposed to different kind of natural hazards. Increasing traffic and extensive road-building programs the latest 25 years have made the society dependent on a relatively ... -
Avalanche debris detection using satellite-borne radar and optical remote sensing
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)The mountainous fjord landscape around Tromsø in Northern Norway is prone to high avalanche activity during the snow season. Large avalanches pose a hazard to infrastructure, such as buildings and roads, located between ...
