Building a high-speed railway station in Girona

Abstract

The high-speed railway station in Girona (Spain) is a diaphragm wall enclosure of approximately 600 meters long, 55 meters wide and an excavated depth of 25 meters. In the cross section there is a bus station, two floors of parking vehicles and a high-speed railway station. The different floors are supported by the external diaphragm walls and the piles of the central zone of the station. A pile diaphragm wall in the lineup of the central piles let pass the TBM that performs the previous and posterior tunnel without delaying the timing of the whole construction.
