Abstract
The construction of the new soccer stadium in Munich-Fröttmaning made it necessary to extend the platforms of the subway station „U6 Marienplatz“ below the historical town hall of Munich. For this, two new tunnels for pedestrians were driven parallel to the existing subway tunnels. In order to reduce the ground displacements, the tunnels were driven below caps of artifi-cially frozen soil. The freezing holes were carried out by pressure drilling out of two priliminary tubes, which had been pressed into the ground laterally above the tunnels. A feasibility study dealed with the subject to convert the freezing pipes for an economical extraction or storage of ground energy. The heating and cooling capacities of the system were estimated with finite element calcula-tions.
