PROJECT OBJECTIVE
New railway platform
This project consists of the construction of a new railway platform from the crossing under the C-31 highway to the T1 terminal at El Prat, Barcelona Airport.
Thus, the proposed route of both tracks is straighter than the previous one, connecting the two terminals by passing under the runways and ending its route under terminal T1, at the same point where Line 9 of the metro does. A large part of the 4.5 km of the proposed route runs through a 2.8 km tunnel, excavated with an EPB type tunnel boring machine. This train allows faster and more direct access from the center of Barcelona, with frequencies of approximately 15 minutes, instead of the 30 minutes of the previous line.

RESULTS AND ACHIEVEMENTS
Infrastructure monitoring
The system installed made it possible to maintain the airport runway in perfect condition during the execution of the railway access tunnel. The result is the evolution of the deformation in the three cross sections and in the vertical one, being able to simulate the possible settling basin at the passage of the tunnel boring machine and to relate it to the local geotechnical parameters and the execution of the tunnel.
It has proved to be a reliable system to minimize the risk of affecting other infrastructures during the construction of the tunnel with an adequate installation time due to the restrictive access to the area. The data obtained by the monitoring system were checked by means of punctual measurements made with topography, so that the system's goodness could be verified.
