Formation and growth of multiple, distinct ice lenses in frost heave
Gao, Hao; Ghoreishian Amiri, Seyed Ali; Kjelstrup, Signe; Grimstad, Gustav; Loranger, Benoit; Scibilia, Elena (Peer reviewed; Journal article, 2022)This paper presents a fully coupled thermo-hydro-mechanical (THM) modelwhich simulates frost heave in fully saturated soils. The model is able tosimulate the formation and growth of multiple distinct ice lenses. The ... -
Numerical modelling of distinct ice lenses in frost heave
Ghoreishian Amiri, Seyed Ali; Grimstad, Gustav; Gao, Hao; Kjelstrup, Signe (Peer reviewed; Journal article, 2021)Frost heave happens when three conditions coincide: the temperature is below the normal freezing point of bulk water, the sub-cooled water is connected to a water reservoir, and the mechanical conditions of the soil allows ... -
Transport coefficients and pressure conditions for growth of ice lens in frozen soil
Kjelstrup, Signe; Ghoreishian Amiri, Seyed Ali; Loranger, Benoit; Gao, Hao; Grimstad, Gustav (Peer reviewed; Journal article, 2021)In this paper, the transport of sub-cooled water across a partially frozen soil matrix (frozen fringe) caused by a temperature difference over the fringe, is described using non-equilibrium thermodynamics. A set of coupled ...
