Hydro‐Mechanical Response of the Tournemire Argillite to the Underground Openings Excavation: Unsaturated Zones and Mine‐by‐test Experiment
A mine‐by‐test has been performed in the Tournemire experimental site, during the excavation of a new gallery in 2003. This experiment shows that excavations in the Tournemire argillite generate hydro‐mechanical disturbances which can extend up to 4 to 6 times the mean radius of the gallery. These hydro‐mechanical disturbances due to the excavation are not as large as the hydric ones due to the desaturation/resaturation processes which take place after excavation. Indeed, the hydric disturbances induced the development of some micro‐cracks mainly parallel to the bedding planes which form the current damaged zone of the gallery.
