Abstract

Shallow geothermal energy applications in buildíngs and civil engineering works (tunnels, diaphragm walls, bridge decks, roads, and train/metro stations) are spreading rapidly all around the world. The dual role of these energy geostructures makes their design challenging and more complex with respect to conventional projects. Besides the geotechnical parameters, thermal behavior parameters (thermal conductivity (l) and volumetric thermal capacity (cv)) are also needed in the design to warrantee the thermo-mechanical stability of the geothermal structural element. This paper presents the numerical modelling of the geothermal behaviour of the driven pile performed in Valencia. In order to obtain ground geological, geotechnical and thermal parameters, both in situ and laboratory methods were used on samples extracted from the cores obtained from a drilling conducted on the experimental site. The data obtained allowed to construct a stratigraphic profile with thermal conductivities ranges of each geologic level, as the basis to create a Finite Elements Model to assess the thermal performance of the system pile-ground working in summer mode (cooling the building and heating the pile).
