Abstract

Problem statement: In this article, some important aspects linked to the new Ceppo Morelli (Piemonte, Italy) future by-pass tunnel construction were considered. Approach: The article concerned a mountainous region which in the past was affected by slope landslides and block falls that reached a downhill roadway and two nearby villages. Results: Using risk analysis approach the probability of block-falls down the mountain slopes was accomplished, with estimation of their trajectories. Conclusion: Obtained results proved the need to open the new tunnel because the present roadway is not considered risk free.
