This book was released on 1962 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snow is a porous. permeable aggregate of ice grains. The grains can be predominantly single crystals or close groupings of several crystals. The pores are filled with air and water vapor. In wet snow the grains are coated with liquid water. The characteristic property of snow is its inherent thermodynamic instability. Consequently most of the interesting physical parameters inevitably change with time. This process of change is called snow metamorphism.

Available in PDF, EPUB and Kindle. Book excerpt: The document covers the site investigations and laboratoty tests in connection with construction on a permanent snowfield, and then deals with the technology of excavation and building where snow is almost the only constructional material. The author draws heavily on the work of the Cold Regions Research and Engineering Laboratory (CRREL) in the development of Camp Century and other projects on the Greenland ice sheet and shows the application of the techniques to Antarctic Research Stations.

Available in PDF, EPUB and Kindle. Book excerpt: An outline is given two current theories on the freezing of water in soils. The classification and description, standardized in the United States and Canada, of frozen soils, leads to some laboratory data on the mechanical behavior of frozen soils. The monograph concludes with the application of linear viscoelastic theory to typical field problems. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Experiments were carried out near Thule, Greenland, on the correlation between the physical properties and internal structure of snow. About 150 snow samples obtained to 26 m depth were measured for elastic modulus, air permeability, unconfined compressive strength, static compression and creep. The observed density profile curve deviated from the theoretical curve at a depth of 10 m. and density of 0.52 g/cu cm, a value almost equivalent to the limiting density obtainable by simple mechanical packing. Therefore, further densification must proceed through plastic flow in grains. A similar critical depth was observed in the vertical distribution of Young's modulus. A positive correlation was found between Young's modulus and an adverse correlation between average grain diameter and Young's modulus or density. There were reciprocal correlations between air permeability and density or unconfined compressive strength, and between the number of grains and their average diameters. Kozeny's constant of Greenland snow was obtained from air permeability values and the length of peripheries of cross sections of grains. To demonstrate the change of internal structure of snow due to densification, static compression tests of snow cylinders were conducted, and thin sections of snow texture were compared before and after compression.
