摘要

This work is devoted to studying some natural geological cavities named ice holes. Because few studies have investigated this phenomenon, our goal is to provide a coherent explanation for it. It is representative of the presence of ice inside some ground cavities at shallow depths during short unfavorable meteorological periods—spring or summer—in some European geographical zones of mean altitude (600 ~ 900 m) that are not subjected to very cold temperatures. However, to date, this phenomenon has not been well explained. The goal of our research is to verify whether the results obtained in a previous simplified study could be confirmed on the basis of the phase change phenomenon and digitalization of local meteorological data observed during a total year. The ice and water contained inside these “ice holes” are representative of a phase change (solidification, fusion, or vaporization), of which water is a well-known model.

The first approach, whose results were published in a previous paper Batina (Environ Water Sci Public Health Territorial Intell J 7(1), 2023), was performed on the basis of a theoretical model involving sinusoidal temperature fluctuations whose mean amplitudes corresponded to 4 seasons: “severe winter”, “winter”, “spring” and “summer”. Natural measurements—physical and structural ice-hole dimensions, depth in relation to the ground level, and material nature—have been equally reported. Currently, digitized local meteorological temperature data play an important role in our numerical modeling. Then, on an identical volume with an equivalent ice content, temperature amplitudes issuing from digitized local meteorological data were applied on the top level of the ice hole. These temperature values will be modified in relation to the depth of the ice-hole top level, which refers to the soil level and the imposed bottom temperature.

From this numerical approach, it appears that many conditions need to be considered and can lead to ice formation and maintenance in this type of hole.
