Numerical modelling of the behaviour of a heat exchanger pile
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 behaviour of a pile subjected to thermo-mechanical loads was studied in situ. The aim was to quantify the thermal influence on the bearing capacity of heat exchanger piles. Coupled multi-physical finite element modelling was carried out to simulate the observed experimental results. It is shown that the numerical model is able to reproduce the most significant thermo-mechanical effects.
