N2 - A new urban railway tunnel, the "second core S-Bahn route", which will cross the city of Munich from the west to the east is being designed. Thereby, a 210 m long platform tunnel with a cross section of 340 m2 will be built via shotcrete excavation at a depth of 40 m in loose soils. It will cross under the existing tunnels of the subway line U3/U6 at a distance of only 4,5 m. In order to compensate the occurring settlements during the tunnel construction, compensation grouting between the existing U3/U6-subway tunnels and the shotcrete excavation of the platform tunnels will be performed. This paper deals with the examinations on how to lift a tunnel tube without damaging it. Therefore, laboratory model tests, as well as 2D- and 3D-finite element calculations were carried out. Important proposals like the design of the grouting area and the grouting sequence will be made.
