Title:
Abstract:	The new Bologna high-speed railway station extends approximately 640 m underground, with a width of 56 m and a depth of 25 m. The open-cut excavation work to complete the underground station was designed using an innovative structural system, which entails the construction of reinforced concrete diaphragm walls with unusual shape and structural behaviour. Vaults, diaphragm walls with an arched section, were constructed to absorb the thrust actions. Buttresses, T-section diaphragm walls were designed to absorb actions through flexural behaviour transmitted by the vaults. Der neue Bahnhof für Hochgeschwindigkeitszüge in Bologna erstreckt sich unterirdisch in einer Tiefe von 25 m über eine Länge von knapp 640 m und eine Breite von etwa 56 m. Zur Herstellung der offenen Baugrube für die unterirdische Haltestelle wurde ein innovatives konstruktives System entworfen, für dessen Ausführung bewehrte Schlitzbetonwände mit ungewöhnlichen Formen und konstruktiven Aufgaben erforderlich sind. Gewölbe aus bogenförmig angeordneten Schlitzwänden werden zur Verteilung von Schubkräften verwendet und Stützpfeiler aus T-förmig angeordneten Schlitzwänden sind für die Aufnahme der von den Gewölben übertragenen Biegebeanspruchung vorgesehen.
