Research Project GeoTU6

GeoTU6 – a geothermal Research Project for Tunnels

Owing to the high degree of earth contact
underground cavities are at the centre of
geothermal deliberations for low energy
systems. Within the scope of a research
project known as GeoTU6 a geothermal test section was set up at the Stuttgart-Fasanenhof Tunnel. The project is described in the
following report.

Underground cavities are at the centre of geothermal deliberations for low energy systems. They involve a high degree of earth contact and can also take over a thermal-energy function in addition to the original static-constructional one with relatively little added technical outlay. Examples from tunnelling are known both from bores created by conventional mining means as well as by mechanised construction methods. They are by and large restricted to the
D-A-CH countries Germany, Austria and Switzerland.

During the production of the Stuttgart-Fasanenhof urban rail link (U6) by the Stuttgarter...
