EarthFlow: Plans for an experimental study of frost driven fracturing
Talk in relation with the EarthFlow project but addressed to a broad audience by Anja Røyne (PGP, UiO)
In this talk I will present the motivation and plans for the "Ice wedging" task of the EarthFlows project, which is set to start in the second half of 2015. The aim of this project is to gain a more quantitative understanding of the how the combined effects of fluid migration, freezing and melting lead to fracturing of low-porosity rocks. A better understanding of the physical mechanisms behind frost-driven fracturing is important for the effective prediction and evaluation of failure leading to rockfall, landslides and damage to structures in cold climates.
