Abstract
In this work a thermo-mechanical (TM) numerical approach is applied to investigate the stress-strain evolution of an alpine rock-slope along which a massive rockslide event occurred around 900 A.D, recently reactivated. Considering the recent geomorphological history of the Valley (post Last Glacial Maximum), not only the effects of glacial unloading, as usual, but also the surface temperature variations are examined by numerical simulation, in order to evaluate whether and how temperature may serve as a preparatory factor for large slope instabilities and how it can be included in modelling.
