Monitoring of Permafrost Foundation-Bed Soils of Low-Rise Buildings Having Unvented Underfloor Spaces

The present article considers the possibility of using an unvented underfloor space enclosed with heat-insulated panels for pile-supported, low-rise buildings in permafrost areas. A long-term, in-situ experiment revealed a pattern of changes occurring over time in the ambient air temperature, the temperature in the underfloor space, as well as the depthwise temperature changes of the foundation-bed soils both under and outside the buildings.
