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...

This paper deals with the evaluation of the hydrogeological hazard in the archaeological site of Castelseprio (northern Italy). Based on the geological, hydrogeological and geomorphological setting of the site, the failure modes and their causative factors were identified, and a proper conceptual model was reconstructed, identifying piping processes as the main phenomena ruling the slopes evolution and the landslides triggering. Afterwards, the hydrogeological hazard was assessed applying numerical modelling both ...
