Norwegian Geotechnical Institute, Oslo / Norway
The Geotest sites research infrastructure managed by the NGI is a national research facility for geotechnical research. The six benchmark test sites are located in Norway and on Svalbard and have been developed as field laboratories for the testing and verification of innovative soil investigation and testing methods, and prototypes of geotechnical structures. The sites cover the soil conditions of soft clay, quick clay, silt and sand. As interest for the Arctic areas grows, one of the sites is in permafrost on Svalbard where detection, sampling, in situ testing and laboratory testing of frozen ground present significant challenges. NGI offers in addition a unique full-scale snow avalanche test site (Fonnbu/Ryggfonn) for studying triggering factors, avalanche dynamics and its impact on the design of mitigation measures.
The test sites serve as reference sites for the industry, public authorities, research organizations and academia. The benchmarked data can be used to develop soil material models, new investigation methods, new foundation solutions and advance the state-of-the-art.
Other Relevant Information
There is already a wide cooperation within the geotechnical community in Norway and abroad for the use of the sites. It is hoped that research at the test facility will provide more cost-effective and sustainable solutions within the building and construction, transportation and energy sectors and to mitigate the effects of climate change.
Various problems can be explored at these sites include (but are not limited to):
- Testing and benchmarking of in situ investigation/testing methods and instrumentations (CPTU, sampling methods, nonintrusive tomographical methods…etc)
- Field testing of foundation prototypes (monopiles, suction bucket, energy piles…etc). See, for example, a full-scale test of pile capacity
- Field testing of soil-structure interaction (piles, retaining wall, fill, cut…etc). See, for example, a full-scale test of a fill for road construction in Norway.
- Experiments for collecting geotechnical parameters to validate constitutive/numerical models (soil-structure interactions…etc).
- Full-scale testing of snow avalanches and safety measures (dams, screens).
