Enrolment in a relevant master programme. Basic knowledge in mathematics and physics at bachelor level.
The objective of the course is to provide an introduction to geotechnical survey methods in permafrost regions using geophysical and in-situ boring techniques. Special emphasis is given to the theoretical background of ground penetrating radar systems and electrical resistivity tomography (ERT) and their applicability in cold regions.
Upon completing the course, the students will:
- have knowledge of different methods for field and laboratory investigations of permafrost soil, snow and ice in cold regions
- know and understand the principles of geophysical investigation methods with special emphasis on ground-penetrating radar (GPR)
- have knowledge of geotechnical soundings, boring and laboratory methods commonly used in the engineering design of infrastructure in cold regions and permafrost
- have an understanding of cold regions field and laboratory investigation needed for engineering planning, design and construction.
Upon completing the course, the students will have:
- experience in cold regions field and laboratory investigations
- experience with operation of ground-penetrating radar (GPR) and data processing software
- experience with geotechnical field and laboratory tests on frozen soil samples
- experience in planning of geotechnical field and laboratory investigations in cold regions and frozen soils.
Upon completing the course, the students will be able to:
- evaluate the strength and weakness of different techniques for cold regions field investigations
- evaluate which type of investigations should be applied for different ground conditions and different types of projects
- interpret data from cold regions field and laboratory investigations, and to derive physical parameters for the investigated material.
The course extends over ca 5 weeks including compulsory safety training.
Based on the theoretical background, the students will carry out field measurements on glaciers, permafrost soils and bedrock. Collected data will be interpreted with the purpose of identifying ground characteristics of importance for infrastructure developments and structure foundations.
Geotechnical boring (soundings and sampling) will be demonstrated in field. Samples will be investigated in the laboratory.
Fieldwork consists of operating ground-penetrating radar (GPR) equipment and geotechnical methods for soil sounding and sampling in cold regions. Geotechnical laboratory work will focus on methods for characterizing frozen soil samples and mechanical properties necessary for foundation design.
The students must submit written assignments and prepare written field and laboratory reports from the course activities.
Total lecture hours: 32 hours.
Total exercise hours: 40 hours.
Laboratory work: 2 days.
Fieldwork: 2-3 days.
Compulsory learning activities:
Laboratory work, fieldwork, assignments and fieldwork reports.
All compulsory learning activities must be approved in order to sit the exam.
