Suivi des déformations du massif rocheux sous la fondation de la pile VII du Pont du Gard

A long-term monitoring study of the Pont du Gard, a Roman aqueduct in France, reveals that seasonal temperature fluctuations significantly influence rock deformations beneath its foundations. Using instrumented bolts and temperature probes installed in the rocky support of Pile VII, researchers observed daily and seasonal variations linked to atmospheric conditions and river floods. These findings were corroborated by analytical simulations, explaining the magnitude of observed deformations. The study highlights the interplay between thermal effects and geological stability, offering insights into the structural behavior of this UNESCO-listed site under environmental stress.
