Tunnel excavation in mountainous or sloping regions can reactivate or accelerate landslide phenomena. On its turn, tunnel excavation can be affected if it crosses weak rocks in landslide-prone areas. In the present study the interaction between tunnelling and slope stability is analysed in presence of Deep-Seated Gravitational Slope Deformation (DSGSD). At this aim a case study is considered, located in northern Italy (Central Alps), where a landslide has been reactivated along the border of a wide DSGSD, close to...

Underground mines from Jiu Valley have as objective the extraction of hard coal, used for energetic purposes. Exploitation activities are associated with the extraction of significant amounts of sterile, derived from opening and preparing works, but also from coal processing activity. The sterile rocks are stored in waste dumps of different sizes, which must undergo periodic stability analysis. This paper aims to estimate waste dumps stability, by using fuzzy theory, the results of such an analysis being of qualit...

For one motorway project in Romania, the alignment has to cross an artificial lake that was made for drying a former swamp. The alternatives considered were crossing the lake with a bridge or with an embankment. According to the geotechnical investigations, the soil in the area consisted of soft saturated clays of 10-18m followed by marle. Crossing the lake with a bridge involved raising the vertical alignment of the motorway to nine meters above ground level in order to ensure the clearance for the maintenance of...
