“…Indeed, observations of changes in ice saturation with temperature produced by Beskow (1935, see figs 19, 20 and 23) and numerous others since (e.g. for a compilation see Andersland and Ladanyi, 2004) indicate clearly that the amount of unfrozen liquid contained within the pore space at subzero temperatures is strongly affected by the distribution of grain sizes; this is partly explained by the persistence of liquid in the vicinity of particle contacts where the interfacial curvature is high. Near the melting temperature, a theoretical model supported by experimental observations in mono-dispersed powders (Cahn and others, 1992; see also Dash and others, 2006) predicts that the fraction of liquid water in the immediate vicinity of highly curved regions dominates the total liquid fraction present.…”

ABSTRACT. The deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence and noted their importance. Idealized experiments continue to prompt theoretical advances that have been combined to develop predictive models for the macroscopic frost-heave characteristics that are seen in the field. This contribution highlights steps on the road to our current understanding of the physical interactions that control how ice forms in unconsolidated porous media.

“…The temperature dependence of both of these parameters can be extracted from independent laboratory studies (e.g. Andersland and Ladanyi, 2004;Watanabe and Flury, 2008;Watanabe and Wake, 2009). While this greatly reduces the effort in comparison with previous modeling attempts (e.g.…”

Artificial Ground Freezing is one of the construction techniques that were extensively adopted during construction of Line 1 of Napoli Underground, to ensure stability and waterproofing of the platform tunnels and inclined passageways during excavation below the ground water table through loose granular soils of pyroclastic origin (Pozzolana) and a fractured soft rock (Neapolitan Yellow Tuff). The aim of the paper is to study the behavior of the Pozzolana and Neapolitan Yellow Tuff subject to freezing and thawing cycle at constant vertical stress under oedometric condition. As the temperature decreases the ice content increases and a liquid ice-surface tension,  li , develops at the interface of the two phases as the temperature decreases. This tension must be balanced by the suction s defined as the difference in frozen and liquid water pressure P i and P l respectively. Two oedometers working under suction and temperature controlled conditions have been modified to work with temperature below zero degree. The stress path followed by samples reproduce the in situ vertical stress interested by freezing and thawing.

“…Desde el punto de vista aplicado a la ingeniería civil, este proceso de degradación del permafrost tiene también grandes efectos directos, como la pér-dida de resistencia y cohesión del terreno, algo que en zonas habitadas supone un riesgo geológico importante por colapso de infraestructuras, edificios, canalizaciones, etc. Esto ha hecho que se desarrollen numerosos estudios dirigidos a evitar la degradación de los suelos congelados, ya sea por efectos naturales o derivados de la actividad antrópica (ej., Péwé, 1983;Williams, 1986;Andersland y Ladanyi, 1994;U.S. Arctic Research Commission Permafrost Task Force, 2003;Zhao-Ping et al, 2010;Schoeneich et al, 2011).…”
