Metro do Porto is a major light rail infrastructure built in the city of Porto and surrounding municipalities. In Porto's downtown, classified by UNESCO as World Heritage, the metro was built underground. From a technical point of view, one of the most challenging underground metro stations due to the geomechanical unique heterogeneous characteristics of the granite rock mass in the Heroísmo station. This station was the first to be built. To better understand the behaviour and interaction of the structures with the surrounding rock masses numerical models were carried out. The geomechanical properties of the granite formations were given by the designer and also obtained through the software GEOPAT. The models' outputs were compared with the monitored results in order to validate the structural behaviour of the underground station.
