Geotechnical Engineering at UNIS focuses on the engineering aspects of permafrost and frozen ground. In addition, geohazards related to snow avalanches, landslides and rock slides are an integrated part of the teaching and research. Industrial development and infrastructure development in the Arctic are dependent on knowledge of cold regions soil mechanics and physics. The temperature dependency of the mechanical and physical behaviour of soils, rock and snow plays an important role in the engineering design. Climate change impact assessment is also a part of the engineering design procedure in permafrost regions.
In sloping terrain, slope stability analysis and land slide risk assessments need to be carried out. Laboratory and field investigations of frozen ground, snow and glaciers are used in teaching and research to investigate these aspects of soil mechanics and geotechnical engineering.
Geotechnical and environmental data
The AT department has during the recent years developed several systems for automatic collection of data from our different field test and instrument sites. The installations give unique opportunities to gather outstanding data from the Arctic environment, and to observe and analyse the continuous changes at the sites. East of UNIS we measure bearing strength and creep properties of pile tip foundations; in the hillside of Platåberget we measure static and glide-induced snow pressure forces on the 1,5 by 3,0 meter snow wall; at Platåberget we measure solar radiation; and in Adventdalen we measure solar radiation on plane of array and solar power production in single and double sided solar panels.
Data are available on-line:
- Arctic solar energy test sites
- Pile test site
- Snow load testing system
