| Abstract: | Contract B-9528 - Södermalm Tunnel is a good example of urban tunnelling, where tunnel alignments cannot be chosen freely due to existing buildings and subsurface structures. Around ten tunnel crossings and a number of difficult situations underpassing existing buildings were in the scope of Södermalm Tunnel with the main focus on the Maria Magdalena Church. A NATM approach enabled tunnelling of the first double track tunnel in Stockholm's Esker to succeed in very close vicinity of the church. Hauptbaulos B-9528 - Södermalmstunnel ist ein Beispiel für innerstädtische Randbedingungen, wo die Linienführung des Tunnels von existierenden Bauwerken beeinflusst ist und nicht mehr frei wählbar ist. Neben rund zehn Tunnelkreuzungen war eine Reihe von schwierigen Gebäudeunterfahrungen im Auftragsumfang des Projekts B5-9528 - Södermalmstunnel, wobei die Maria-Magdalena-Kirche im Fokus der Bemühungen stand. Ein NÖT-Vortrieb ermöglichte im Nahbereich der Kirche die erste Durchörterung von Stockholms Esker (Oser) mit einem Großquerschnitt. |
