Book Description
The topics covered in the monograph include water supply, waste disposal, heating, ventilating and fire protection at installations built on polar ice sheets. The section on water supply discusses energy requirements, consumption rates, water quality and treatment, techniques and equipment for melting snow and ice, and water distribution systems. A number of actual water supply systems are described in detail. The section on waste disposal deals with sewage and sewage sinks, latrines, garbage, trash and scrap and radioactive waste. Examples of sanitation systems at polar bases are described in some detail. The section on heating discusses heating load, heat losses and insulation, energy sources, and heating systems. The ventilation section covers air demands, intakes and exhausts, ventilation of undersnow tunnels, and carbon monoxide problems. The report concludes with some notes on fire protection. (Author).

Book Description
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.

Book Description
Various types of foundations suitable for use in very deep snow are described, and design principles are given. Dependence of settlement rate on heaving pressure, size and shape of foundation, snow temperature, and snow density is treated analytically, and field data from test procedures for foundation design are outlined. In treating the design of tunnels, shafts and subsurface structures in very deep snow, the distributions of stress, strain and displacement in polar ice sheets are first obtained analytically. Observed patterns of deformation are given for a variety of excavations and deformable structures, and methods of analysis are put forward. The loading of restraining structures is discussed, and finally some notes on the monitoring and maintenance of subsurface structures are given. (Author).

Book Description
The monograph describes the various kinds of foundations used for structures on permafrost with a brief discussion of foundations in areas of seasonal frost. Special attention is given to piled foundations in permafrost and the design of ventilation systems for controlling thaw under heated buildings. Appendixes outline techniques for computing the depth of freezing or of thawing, the design of refrigeration systems for artificial freezing, and the recommended procedure in the USSR for static pile tests. Included in the main text are 51 figures and 62 selected references. (Author).

Book Description
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).
