Abstract

The geothermal use of concrete geostructures (piles, walls, and slabs) is an environmentally friendly way of cooling and heating buildings. With such geothermal structures, it is possible to transfer energy from the ground to fluid-filled pipes cast in concrete and then to building environments. To improve the knowledge in the field of geothermal structures, the behavior of a pile subjected to thermo-mechanical loads was studied in situ. The aim was to quantify the thermal influence on ...
