Perkuatan pada fondasi diperlukan untuk menaikan kapasitas daya dukung gambut. Daya dukung fondasi merupakan permasalahan baru yang harus diselesaikan dalam pembangunan infrastruktur diatas lahan gambut. Tanah gambut merupakan tanah yang terbentuk dari tumbuhan yang mengalami pembusukan ribuan tahun. Sebagian besar dari wilayah provinsi Riau merupakan tanah gambut. The combination of experimental and numerical models provides helpful results for the definition of guidelines concerning the prevention of interactions.

A numerical hydraulic-thermal coupled model was developed with the FEM software CESAR-LCPC to extrapolate the results. To study these interactions, a group of nine energy piles has been studied in Sense City, a mini city where a specific climate can be imposed and the underground water flow can be controlled.
The understanding of these interactions is essential for a smart management of the shallow geothermal development at the city scale. This advection creates a thermal plume and heat waves in the soil can interact with downstream structures whose behaviour can be affected. On one hand, it is a good way to avoid any multiyear thermal shift since the heat excess or default is tempered through the advection. Energy geostructures are often placed in a groundwater flow. These low energy solutions combining a structural and a thermal role allow the fulfilling of the heating and cooling needs of buildings for a very low carbon cost. Since the 1980’s, shallow geothermal solutions have been developed whose principle is to attach heat exchange pipes to the reinforcing cages of geotechnical structures.
